[MC] Fix handling of end-of-line preprocessor comments
Summary:
When parsing assembly where the line comment syntax is not hash, the
lexer cannot distinguish between hash's that start a hash line comment
and one that is part of an assembly statement and must be distinguished
during parsing. Previously, this was incompletely handled by not checking
for EndOfStatement at the end of statements and interpreting hash
prefixed statements as comments.
Change EndOfStatement Parsing to check for Hash comments and reintroduce
Hash statement parsing to catch previously handled cases.

CCACHE_HASHDIR is required to maintain the separate cached data across

as orphaned pages (pages which the FPM says are allocated, but which
nothing appears to use), use after free pages (pages which the FPM says

switch (i) {
case 5: ...

case 13: ...

Fix - CodeExtractor : Inherit Target Dependent Attributes from the parent function.
When extracting a set of blocks make sure to inherit all of the target
dependent attributes to make sure that the function will be valid for
lowering. One example is the "target-features" attribute for x86, if the
extracted region has functionality that relies on a specific feature it
will fail to be lowered.
This also allows for extracted functions to be valid for inlining, at
least back into the parent function, as the target attributes are tested
when inlining for compatibility.

`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

DAG: avoid duplicated truncating for sign extended operand
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.

[Support] Add storage specifier for MachO::NListType.
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.

GlobalISel: support translation of intrinsic calls.
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.

Think this will fix issues with the error messages generated for malformed-archives.test
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
fixing the warning on the ld-x86_64-win7 bot.

[X86] Match PSADBW in straight-line code
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.
