23a49a637b Add a unittest for SmallDenseMap that tests assigning a SmallDenseMap when it is not small.
This complements CopyConstructorNotSmallTest. If we are testing the copy
constructor in such a way, we should also probably test assignment in the same
way.

05f3dabc64 Implemented the code to make llvm-nm’s -g option work.
While llvm-nm parses the -g option and has help that describes it as:

  -extern-only            - Show only external symbols

There is no code in the program to use the boolean valve it sets from the
command line.

e8abcab8ed [FunctionAttrs] Separate another chunk of the logic for functionattrs
from its pass harness by providing a lambda to query for AA results.

This allows the legacy pass to easily provide a lambda that uses the
special helpers to construct function AA results from a legacy CGSCC
pass. With the new pass manager (the next patch) the lambda just
directly wraps the intuitive query API.

0c35941274 [SCEV] Generalize the SCEV algorithm for creating expressions for PHI nodes
Summary:
When forming expressions for phi nodes having an incoming value from
outside the loop A and a value coming from the previous iteration B
we were forming an AddRec if:
  - B was an AddRec
  - the value A was equal to the value for B at iteration -1 (or equal
    to the value of B shifted by one iteration, at iteration 0)

In this case, we were computing the expression to be the expression of
B, shifted by one iteration.

This changes generalizes the logic above by removing the restriction that
B needs to be an AddRec. For this we introduce two expression rewriters
that allow us to
  - shift an expression by one iteration
  - get the value of an expression at iteration 0

This allows us to get SCEV expressions for PHI nodes when these expressions
are not AddRecExprs.

32e078b09c [LLVMSymbolize] Move ModuleInfo into a separate class (SymbolizableModule).
Summary:
This is mostly NFC. It is a first step in cleaning up LLVMSymbolize
library. It removes "ModuleInfo" class which bundles together ObjectFile
and its debug info context in favor of:
  * abstract SymbolizableModule in public headers;
  * SymbolizableObjectFile subclass in implementation.

Additionally, SymbolizableObjectFile is now created via factory, so we
can properly detect object parsing error at this stage instead of keeping
the broken half-parsed object. As a next step, we would be able to
propagate the error all the way back to the library user.

Further improvements might include:
  * factoring out the logic of finding appropriate file with debug info
    for a given object file, and caching all parsed object files into a
    separate class [A].
  * factoring out DILineInfo rendering [B].
This would make what is now a heavyweight "LLVMSymbolizer" a relatively
straightforward class, that calls into [A] to turn filepath into a
SymbolizableModule, delegates actual symbolization to concrete SymbolizableModule
implementation, and lets [C] render the result.

d63f887b3e [X86][SSE] Shuffle blends with zero
This patch generalizes the zeroing of vector elements with the BLEND instructions. Currently a zero vector will only blend if the shuffled elements are correctly inline, this patch recognises when a vector input is zero (or zeroable) and modifies a local copy of the shuffle mask to support a blend. As a zeroable vector input may not be all zeroes, the zeroable vector is regenerated if necessary.

only that one -check-prefix (removing the additional -check-prefix=B):

6f27cebd4c [FunctionAttrs] Provide a single SCC node set to all of the
transformations in FunctionAttrs rather than building a new one each
time.

This isn't trivial because there are different heuristics from different
passes for exactly what set they want. The primary difference is whether
an *overridable* function completely disables the synthesis of
attributes. I've modeled this by directly testing for overridable, and
using the common set that excludes external and opt-none functions.

This does cause some changes by disabling more optimizations in the face
of opt-none. Specifically, we were still optimizing *calls* to opt-none
functions based on their attributes, just not the bodies. It seems
better to be conservative on both fronts given the intended semanticas
here (best effort to not assume or disturb anything). I've not tried to
test this change as it seems complex, brittle, and not important to the
implicit contract of opt-none. Instead, it seems more like a choice that
should be dictated by the simplified implementation and the change to be
acceptable differences within the space of opt-none.

A big benefit here is that these transformations no longer rely on the
legacy pass manager's SCC types, they just work on generic sets of
function pointers. This will make it easy to re-use their logic in the
new pass manager.

I've also made the transforms static functions instead of members where
trivial while I was touching the signatures.

ea81d62d37 [SystemZ] Make the CCRegs regclass non-allocatable.
This was discovered to be necessary while running memchr-01.ll with
-verify-machinstrs, because it is not allowed to have a phys reg live
accross block boundaries while on SSA form, if the register is
allocatable (expect in entry block and landing pads).

In this test case, stringRRE pseudos are expanded after isel by adding
a loop block which produces a live out CC register. To make the test
pass, it was also necessary to not say that StringRRELoop pseudo uses
R0L, this is only true for the StringRRE opcode.

-verify-machineinstrs added to memchr-01.ll test.

New test case int-cmp-51.ll to test that MachineCSE can eliminate
an identical compare (which it couldn't do before).

741f26cf8e [sanitizer] [msan] Unify aarch64 mapping
This patch unify the 39-bit and 42-bit mapping for aarch64 to use only
one instrumentation algorithm.  This removes compiler flag 
SANITIZER_AARCH64_VMA requirement for MSAN on aarch64.

The mapping to use now is for 39 and 42-bits:

    0x00000000000ULL-0x01000000000ULL  MappingDesc::INVALID
    0x01000000000ULL-0x02000000000ULL  MappingDesc::SHADOW
    0x02000000000ULL-0x03000000000ULL  MappingDesc::ORIGIN
    0x03000000000ULL-0x04000000000ULL  MappingDesc::SHADOW

    0x07000000000ULL-0x08000000000ULL  MappingDesc::APP

And only for 42-bits:

    0x08000000000ULL-0x09000000000ULL  MappingDesc::INVALID
    0x09000000000ULL-0x0A000000000ULL  MappingDesc::SHADOW

    0x3F000000000ULL-0x40000000000ULL  MappingDesc::APP

And although complex it provides a better memory utilization that
previous one.
