Comments: Add tests for clang plugins

Somehow the entire plugin infrastructure went wholly untested until now.

The only plugins available for use in testing are the examples, so plugin tests
will only be run if CLANG_BUILD_EXAMPLES is enabled in the build.

(The examples should really be enabled by default, not just to aid testing but
also to prevent bitrot in some key user-facing code. I'll propose that
shortly.)

Comments: Use -std=gnu89 in tools/c-index-test/CMakeLists.txt

With the old use of -std=c89 off_t is not defined and the build fails.

With a current mingw (gcc 4.8.1) it looks like we hit some variation of

Comments: Build fix following r198747

Convert CMake CLANG_BUILD_EXAMPLES to a boolean value for consumption by
Python, otherwise the raw config string gets passed through which may not be
0/1.

The if/else matches the technique used to solve the problem in LLVM's own

Comments: [x86] Add OpSize16 to instructions that need it

This fixes the bulk of 16-bit output, and the corresponding test case
x86-16.s now looks mostly like the x86-32.s test case that it was
originally based on. A few irrelevant instructions have been dropped,
and there are still some corner cases to be fixed in subsequent patches.Properties:

Comments: [x86] Disambiguate RET[QL] and fix aliases for 16-bit mode

I couldn't see how to do this sanely without splitting RETQ from RETL.

I have no idea what that means, but perhaps it wants preserving in the

JCXZ should have the 0x67 prefix only if we're in 32-bit mode, so make that

Comments: [x86] Use 16-bit addressing where possible in 16-bit mode

Where "where possible" means that it's an immediate value and it's below
0x10000. In fact GAS will either truncate or error with larger values,
and will insist on using the addr32 prefix to get 32-bit addressing. So
perhaps we should do that, in a later patch.Properties:

Comments: [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?Properties:

Comments: [x86] Make AsmParser validate registers for memory operands a bit better

We can't do a perfect job here. We *have* to allow (%dx) even in 64-bit
mode, for example, because it might be used for an unofficial form of
the in/out instructions. We actually want to do a better job of validation
*later*. Perhaps *instead* of doing it where we are at the moment.

But for now, doing what validation we *can* do in the place that the code
already has its validation, is an improvement.Properties:
