e916566881 Merge x86 HasOpSizePrefix/HasOpSize16Prefix into a 2-bit OpSize field with 0 meaning no 0x66 prefix in any mode. Rename Opsize16->OpSize32 and OpSize->OpSize16. The classes now refer to their operand size rather than the mode in which they need a 0x66 prefix. Hopefully can merge REX_W into this as OpSize64.

487b278e90 Comment out unused macro because of warning 
Modern compilers (Clang 3.4, GCC 4.8) warn on variadic macros being
introduced in C99, which produces a huge number of useless diagnostics
since this macro is unused in the whole project.

a2ca508d75 Improve handling of EnforceSmallerThan. Remove all types that are smaller from the larger set not just the smallest type from the smaller set. Ensure 'smaller' vectors have the same or fewer total bits. Similar for 'larger' vectors.

5f6416d4b7 Don't use EnforceSmallerThan for EnforceVectorSubVectorTypeIs. EnforceSmallerThan doesn't handle vectors quite right and should really enforce that vectors have the same number of elements. Add explicit checks for vector element count differing in EnforceVectorSubVectorTypeIs instead. This removes some unnecessary type checks in X86GenDAGISel.inc.

d30df6b04f [x86] Fix disassembly of MOV16ao16 et al. 
The addition of IC_OPSIZE_ADSIZE in r198759 wasn't quite complete. It
also turns out to have been unnecessary. The disassembler handles the
AdSize prefix for itself, and doesn't care about the difference between
(e.g.) MOV8ao8 and MOB8ao8_16 definitions. So just let them coexist and
don't worry about it.

28c512a65e Add FPExt option to CCValAssign::LocInfo. When generating calling-convention 
promotion code, Tablegen will now select FPExt for floating point promotions
(previously it had returned AExt, which is not valid for floating point types).

Any out-of-tree targets that were relying on AExt being returned for FP
promotions will need to update their code check for FPExt instead.

1c1ecbff81 Separate the concept of 16-bit/32-bit operand size controlled by 0x66 prefix and the current mode from the concept of SSE instructions using 0x66 prefix as part of their encoding without being affected by the mode. 
This should allow SSE instructions to be encoded correctly in 16-bit mode which r198586 probably broke.

b9c4c9d6f5 lit: Provide source locations in cfg files with older Python versions 
This commit prospectively brings the benefits of r198766 to older supported
Python versions (2.5+).

a9c0934bea lit: execfile() isn't present in Python 3.3 
On the other hand, exec(compile()) doesn't work in older Python versions in the
2.x series.

This commit introduces exec(compile()) with a fallback to plain exec(). That'll
hopefully hit the sweet spot in terms of version support.

Followup to r198766 which added enhanced source locations for lit cfg parsing.

671c9fe7b0 Revert "Disable LeakSanitizer in TableGen binaries, see PR18325" 
To declare or define reserved identifers is undefined behaviour in standard
C++. This needs to be addressed in compiler-rt before it can be used in LLVM.

See the list discussion for details.

This reverts commit r198858.

7638179115 lit: Provide file location in cfg error messages 
Python doesn't do a good job at diagnosing string exec() so use execfile()
where available.

This should be a timesaver when trying to get to the bottom of build bot
failures.

Before:

    File "llvm/utils/lit/lit/TestingConfig.py", line 93, in load_from_path
      exec("exec data in cfg_globals")
    File "<string>", line 1, in <module>
    File "<string>", line 194, in <module>
  NameError: name 'typo' is not defined

After:

    File "llvm/utils/lit/lit/TestingConfig.py", line 95, in load_from_path
    execfile(path, cfg_globals)
    File "clang/test/lit.cfg", line 194, in <module>
      typo
      ^~~~

399c563e5e [x86] Fix MOV8ao8 et al for 16-bit mode, fix up disassembler to understand 
It seems there is no separate instruction class for having AdSize *and*
OpSize bits set, which is required in order to disambiguate between all
these instructions. So add that to the disassembler.

Hm, perhaps we do need an AdSize16 bit after all?
