We had import_directory_table_entry and
coff_import_directory_table_entry, remove one. Also, factor out the
logic which determins if a descriptor is a terminator.

The 2i32-2i64 legalization means that we can use the slightly quicker double bits + fptrunc approach for the same results

Summary:
This change fixes issues with `LLVM_CONSTEXPR` functions and
`TrailingObjects::FixedSizeStorage`. In particular, some of the
functions marked `LLVM_CONSTEXPR` used by `FixedSizeStorage` were not
implemented such that they evaluate successfully as part of a constant
expression despite constant arguments.
This change also implements a more traditional template-meta path to
accommodate MSVC, and adds unit tests for `FixedSizeStorage`.
Drive-by fix: the access control for members of `TrailingObjectsImpl` is
tightened.

Summary:
This change adds `LLVM_CONSTEXPR` to functions selected as follows:
- the body is already valid under C++11 for a `constexpr` function,
- the evaluation of the function, given constant arguments, will not
fail during the evaluation of a constant expression, and
- the above properties are easily verifiable at a glance.
Note: the evaluation of the function cannot fail if the instantiation
triggers a static assertion failure.

This makes it possible to implement re-optimization on top of the
CompileOnDemandLayer.
Test case to come in a future patch: This will need an execution test, and
execution tests require a full working stack. The best option is to plumb this
API up to the C Bindings stack and add a C bindings test for this.

Summary:
When performing cmp for EQ/NE and the operand is sign extended, we can
avoid the truncaton if the bits to be tested are no less than origianl
bits.

This should fix UB warnings from the sanitizer bots: LLD performs bit
manipulations on enums of this type, and these are UB if the underlying
storage type isn't specified.

These come in two variants for now: G_INTRINSIC and G_INTRINSIC_W_SIDE_EFFECTS.
We may decide to split the latter up with finer-grained restrictions later, if
necessary.

in r277177 and added back this test which was deleted in r277196 while
I tracked down these problems.
Changed from constructing Twine's to std::string's as Twine's don't work
across statements. Also removed a few unneeded Twine() constructions.
Fix the write_escaped() calls to not pass the unintended second argument

Up until now, we only had code to match PSADBW patterns that look like what
comes out of the loop vectorizer - a partial reduction inside the loop body
that gets fed into a horizontal operation in a different basic block.
This adds support for straight-line patterns, like those generated by the
SLP vectorizer.

Support for lowering to VBROADCASTF128 etc. in D22460 was not correctly ensuring that the only users of the 128-bit vector load were the insertions of the vector into the lower/upper subvectors.

Previously this change was submitted from a Windows machine, so
changes made to the case of filenames and directory names did
not survive the commit, and as a result the CMake source file
names and the on-disk file names did not match on case-sensitive
file systems.
I'm resubmitting this patch from a Linux system, which hopefully
allows the case changes to make it through unfettered.

This will be used during GlobalISel, where we need a more robust and readable
way to write tests than a simple immediate ID.

LoopUnroll is a loop pass, so the analysis of OptimizationRemarkEmitter
is added to the common function analysis passes that loop passes
depend on.
The BFI and indirectly BPI used in this pass is computed lazily so no
overhead should be observed unless -pass-remarks-with-hotness is used.
This is how the patch affects the O3 pipeline:

We used the wrong type for constructing a zero vector element which led
to type mismatches.
