f2d75670b7 The only supported calling convention for X86-64 uses 
SSE, so we can't return floating point values if this
is disabled.  Detect this error for clang.

With SSE1 only, f64 is a problem; it can be done, but
neither llvm-gcc nor clang has ever generated correct
code for it.  Since nobody noticed this I think it's
OK to treat it as an error for now.

This also handles SSE-sized vectors of floating point.

0710c74f29 Add remaining AVX instructions (most of them dealing with GR64 destinations. This complete the assembler support for the general AVX ISA. But we still miss instructions from FMA3 and CLMUL specific feature flags, which are now the next step

083be4d384 instead of migrating it to the MC instruction encoder, just 
rip out the implementation of X86InstrInfo::GetInstSizeInBytes.
The code being ripped out just implemented a copy and hacked up
version of the (old) instruction encoder, and is buggy and 
terrible in other ways.  Since "GetInstSizeInBytes" is really 
only there to support the JIT's "NeedsExactSize" hook (which
noone is using), just rip out the code.  I will rip out the
NeedsExactSize hook next.

This resolves rdar://7617809 - switch X86InstrInfo::GetInstSizeInBytes to use X86MCCodeEmitter

especially on other platforms. Is there a better way to fix this.

350b1a449f Fixes win64. It was broken by a previous patch where I missed the !isWin64 
and then forced every register to be a vr128 on win64.

5c91a5e747 add some rough support for making mcinst lowering work without an 
asmprinter or mangler around.  This is option #B for killing off 
X86InstrInfo::GetInstSizeInBytes.  Option #A (killing 
"needsexactsize") was sent for consideration to llvmdev.

784e062b2a Fix a couple issues with Win64 ABI 
1) all registers were spilled as xmm, regardless of actual size
2) win64 abi doesn't do the varargs-size-in-%al thing

Still to look into:

xmm6-15 are marked as clobbered by call instructions on win64 even though they aren't.

64fffadad3 fix a layering problem by moving the x86 implementation 
of AsmPrinter and InstLowering into libx86 and out of the
asmprinter subdirectory.  Now X86/AsmPrinter just depends on
MC stuff, not all of codegen and LLVM IR.

9db7d0addd X86: Mark JMP{32,64}[mr] as requires 32-bit/64-bit mode. They are the same 
instruction, we only want to allow the one for the current subtarget.
 - This also fixes suffix matching for jmp instructions, because it eliminates
   the ambiguity between 'jmpl' and 'jmpq'.

eefe8616be TblGen/AsmMatcher: Add support for honoring instruction Requires<[]> attributes as part of the matcher. 
- Currently includes a hack to limit ourselves to "In32BitMode" and "In64BitMode", because we don't have the other infrastructure to properly deal with setting SSE, etc. features on X86.

419197cc4d Target: Give the TargetAsmParser access to the TargetMachine. 
- Unfortunate, but necessary for now to handle subtarget instruction matching. Eventually we should factor out the lower level target machine information so we don't need to do this.
