R600/SI: Add enums for some hard-coded values

R600/SI: Use ISD::MUL instead of ISD::UMULO when lowering division

ISD::MUL and ISD:UMULO are the same except that UMULO sets an overflow
bit.  Since we aren't using the overflow bit, we should use ISD::MUL.

R600: Don't set BypassSlowDiv for 64-bit division

BypassSlowDiv is used by codegen prepare to insert a run-time
check to see if the operands to a 64-bit division are really 32-bit
values and if they are it will do 32-bit division instead.

This is not useful for R600, which has predicated control flow since
both the 32-bit and 64-bit paths will be executed in most cases.  It
also increases code size which can lead to more instruction cache
misses.

Revert "R600/SI: Add support for global atomic add"

This reverts commit r218254.

The global_atomics.ll test fails with asserts disabled.  For some reason,
the compiler fails to produce the atomic no return variants.

Use broadcasts to optimize overall size when loading constant splat vectors (x86-64 with AVX or AVX2).

We generate broadcast instructions on CPUs with AVX2 to load some constant splat vectors.
This patch should preserve all existing behavior with regular optimization levels, 
but also use splats whenever possible when optimizing for *size* on any CPU with AVX or AVX2.

The tradeoff is up to 5 extra instruction bytes for the broadcast instruction to save
at least 8 bytes (up to 31 bytes) of constant pool data.

Make MCAsmParserSemaCallback::LookupInlineAsmLabel a pure virtual function

Summary:
r218229 made this function return a dummy nullptr in order to avoid

[x86] Introduce tests covering the gamut of 256-bit vector shuffling.

These are just test cases, no actual code yet. This establishes the
baseline fallback strategy we're starting from on AVX2 and the expected
lowering we use on AVX1.

Also, these test cases are very much generated. I've manually crafted
the specific pattern set that I'm hoping will be useful at exercising
the lowering code, but I've not (and could not) manually verify *all* of
these. I've spot checked and they seem legit to me.

As with the rest of vector shuffling, at a certain point the only really
useful way to check the correctness of this stuff is through fuzz
testing.

MC: ReadOnlyWithRel section kinds should map to rdata in COFF

Don't consider ReadOnlyWithRel as a writable section in COFF, they
really belong in .rdata.

ms-inline-asm: Fix parsing label names inside bracket expressions

Summary:
This fixes a couple of issues.  One is ensuring that AOK_Label rewrite
rules have a lower priority than AOK_Skip rules, as AOK_Skip needs to
be able to skip the brackets properly.  The other part of the fix ensures
that we don't overwrite Identifier when looking up the identifier, and
that we use the locally available information to generate the AOK_Label
rewrite in ParseIntelIdentifier.  Doing that in CreateMemForInlineAsm
would be problematic since the Start location there may point to the
beginning of a bracket expression, and not necessarily the beginning of
an identifier.

This also means that we don't need to carry around the InternlName field,
which helps simplify the code.

Test Plan: This will be tested on the clang side.

[FastISel][AArch64] Also allow folding of sign-/zero-extend and shift-left for booleans (i1).

Shift-left immediate with sign-/zero-extensions also works for boolean values.
Update the assert and the test cases to reflect that fact.

This should fix a bug found by Chad.

In this callback ModuleName includes the file path.
Comparing ModuleName to the file names listed will 
always fail. 

I wonder how this code ever worked and what its 
purpose was. Why exclude the msvc runtime DLLs
but not exclude all Windows system DLLs?

Anyhow, it does not function as intended.

clang-formatted as well.

[x86] Rename X86ISD::VPERMILP to X86ISD::VPERMILPI (and the same for the
td pattern). Currently we only model the immediate operand variation of
VPERMILPS and VPERMILPD, we should make that clear in the pseudos used.
Will be adding support for the variable mask variant in my next commit.
