ed576a186f [ORC] Add RPC and serialization support for Errors and Expecteds.
This patch allows Error and Expected types to be passed to and returned from
RPC functions.

Serializers and deserializers for custom error types (types deriving from the
ErrorInfo class template) can be registered with the SerializationTraits for
a given channel type (see registerStringError in RPCSerialization.h for an
example), allowing a given custom type to be sent/received. Unregistered types
will be serialized/deserialized as StringErrors using the custom type's log
message as the error string.

8b69529e74 Support: Add a VCSRevision.h header file.
This is a magic header file supported by the build system that provides a
single definition, LLVM_REVISION, containing an LLVM revision identifier,
if available. This functionality previously lived in the LTO library, but
I am moving it out to lib/Support because I want to also start using it in
lib/Object to create the IR symbol table.

This change also fixes a bug where LLVM_REVISION was never actually being
used in lib/LTO because the macro HAS_LLVM_REVISION was never defined (it
was misspelled as HAVE_SVN_VERSION_INC in lib/LTO/CMakeLists.txt, and was
only being defined in a non-existent file Version.cpp).

I also changed the code to use "git rev-parse --git-dir" to locate the .git
directory, instead of looking for it in the LLVM source root directory,
which makes this compatible with monorepos as well as git worktrees.

e9a46bf123 [IR] Take func, ret, and arg attrs separately in AttributeList::get
This seems like a much more natural API, based on Derek Schuff's
comments on r300015. It further hides the implementation detail of
AttributeList that function attributes come last and appear at index
~0U, which is easy for the user to screw up. git diff says it saves code
as well: 97 insertions(+), 137 deletions(-)

This also makes it easier to change the implementation, which I want to
do next.

e05ab25f5d ArgList: cache index ranges containing arguments with each ID
Improve performance of argument list parsing with large numbers of IDs and
large numbers of arguments, by tracking a conservative range of indexes within
the argument list that might contain an argument with each ID. In the worst
case (when the first and last argument with a given ID are at the opposite ends
of the argument list), this still results in a linear-time walk of the list,
but it helps substantially in the common case where each ID occurs only once,
or a few times close together in the list.

This gives a ~10x speedup to clang's `test/Driver/response-file.c`, which
constructs a very large set of command line arguments and feeds them to the
clang driver.

67dcd802e3 [llvm-pdbdump] Minor prepatory refactor of Class Def Dumper.
In a followup patch I intend to introduce an additional dumping
mode which dumps a graphical representation of a class's layout.
In preparation for this, the text-based layout printer needs to
be split out from the graphical layout printer, and both need
to be able to use the same code for printing the intro and outro
of a class's definition (e.g. base class list, etc).

This patch does so, and in the process introduces a skeleton
definition for the graphical printer, while currently making
the graphical printer just print nothing.

7724dc63a7 [llvm-pdbdump] More advanced class definition dumping.
Previously the dumping of class definitions was very primitive,
and it made it hard to do more than the most trivial of output
formats when dumping.  As such, we would only dump one line for
each field, and then dump non-layout items like nested types
and enums.

With this patch, we do a complete analysis of the object
hierarchy including aggregate types, bases, virtual bases,
vftable analysis, etc.  The only immediately visible effects
of this are that a) we can now dump a line for the vfptr where
before we would treat that as padding, and b) we now don't
treat virtual bases that come at the end of a class as padding
since we have a more detailed analysis of the class's storage
usage.

In subsequent patches, we should be able to use this analysis
to display a complete graphical view of a class's layout including
recursing arbitrarily deep into an object's base class / aggregate
member hierarchy.

53726fa11a [ValueTracking] Teach GetUnderlyingObject to stop when it reachs an alloca instruction.
Previously it tried to call SimplifyInstruction which doesn't know anything about alloca so defers to constant folding which also doesn't do anything with alloca. This results in wasted cycles making calls that won't do anything. Given the frequency with which this function is called this time adds up.

6f93f61542 Remove readnone from invariant.group.barrier
Summary:
Readnone attribute would cause CSE of two barriers with
the same argument, which is invalid by example:

    struct Base {
          virtual int foo() { return 42; }
    };

    struct Derived1 : Base {
          int foo() override { return 50; }
    };

    struct Derived2 : Base {
          int foo() override { return 100; }
    };

    void foo() {
        Base *x = new Base{};
        new (x) Derived1{};
        int a = std::launder(x)->foo();
        new (x) Derived2{};
        int b = std::launder(x)->foo();
    }

Here 2 calls of std::launder will produce @llvm.invariant.group.barrier,
which would be merged into one call, causing devirtualization
to devirtualize second call into Derived1::foo() instead of
Derived2::foo()

ab480f45cd [Support] Add support for unique_ptr<> to Casting.h.
Often you have a unique_ptr<T> where T supports LLVM's
casting methods, and you wish to cast it to a unique_ptr<U>.
Prior to this patch, this requires doing hacky things like:

unique_ptr<U> Casted;
if (isa<U>(Orig.get()))
  Casted.reset(cast<U>(Orig.release()));

This is overly verbose, and it would be nice to just be able
to use unique_ptr directly with cast and dyn_cast.  To this end,
this patch updates cast<> to work directly with unique_ptr<T>,
so you can now write:

auto Casted = cast<U>(std::move(Orig));

Since it's possible for dyn_cast<> to fail, however, we choose
to use a slightly different API here, because it's awkward to
write

if (auto Casted = dyn_cast<U>(std::move(Orig))) {}

when Orig may end up not having been moved at all.  So the
interface for dyn_cast is

if (auto Casted = unique_dyn_cast<U>(Orig)) {}

Where the inclusion of `unique` in the name of the cast operator
re-affirms that regardless of success of or fail of the casting,
exactly one of the input value and the return value will contain
a non-null result.

51f7e1a9dc [InstCombine] Teach SimplifyDemandedInstructionBits that even if we reach an instruction that has multiple uses, if we know all the bits for the demanded bits for this context we can go ahead and create a constant.
Currently if we reach an instruction with multiples uses we know we can't do any optimizations to that instruction itself since we only have the demanded bits for one of the users. But if we know all of the bits are zero/one for that one user we can still go ahead and create a constant to give to that user.

This might then reduce the instruction to having a single use and allow additional optimizations on the other path.

This picks up an additional case that r300075 didn't catch.

6b814345d1 MachineScheduler: Skip acyclic latency heuristic for in-order cores
The current heuristic is triggered on `InFlightCount > BufferLimit`
which isn't really helpful on in-order cores where BufferLimit is zero.

Note that we already get latency hiding effects for in order cores
by instructions staying in the pending queue on stalls; The additional
latency scheduling heuristics only have minimal effects after that while
occasionally increasing register pressure too much resulting in extra
spills.

My motivation here is additional spills/reloads ending up in a loop in
464.h264ref / BlockMotionSearch function resulting in a 4% overal
regression on an in order core. rdar://30264380

3461e9c2e4 Teach SimplifyDemandedUseBits that adding or subtractings 0s from every bit below the highest demanded bit can be simplified
If we are adding/subtractings 0s below the highest demanded bit we can just use the other operand and remove the operation.

My primary motivation is observing that we can call ShrinkDemandedConstant for the add/sub and create a 0 constant, rather than removing the add completely. In the case I saw, we modified the constant on an add instruction to a 0, but the add is not put into the worklist. So we didn't revisit it until the next InstCombine iteration. This caused an IR modification to remove add and a subsequent iteration to be ran.

With this change we get bypass the add in the first iteration and prevent the second iteration from changing anything.

e930b092c4 [InstCombine] morph an existing instruction instead of creating a new one
One potential way to make InstCombine (very slightly?) faster is to recycle instructions 
when possible instead of creating new ones. It's not explicitly stated AFAIK, but we don't
consider this an "InstSimplify". We could, however, make a new layer to house transforms 
like this if that makes InstCombine more manageable (just throwing out an idea; not sure 
how much opportunity is actually here).
