5673933e30 fix a bug I introduced in r115669, which ended up with MOV64mr_TC 
not getting marked as mayStore.  This fixes llvm-gcc bootstrap.

b94ade249a The pshufw instruction came about in MMX2 when SSE was introduced. Don't place 
it in with the SSSE3 instructions.

Steward! Could you place this chair by the aft sun deck? I'm trying to get away
from the Astors. They are such boors!

49d508fd19 Jim Asked us to move DataLayout on ARM back to the most specialized classes. Do 
so and also change X86 for consistency.

Investigating if this can be improved a bit.

but not the "3dnowa" ones.

8174253484 Implement support for the bizarre 3DNow! encoding (which is unlike anything 
else in X86), and add support for pavgusb.  This is apparently the
only instruction (other than movsx) that is preventing ffmpeg from building
with clang.

If someone else is interested in banging out the rest of the 3DNow! 
instructions, it should be quite easy now.

2143c9d321 Rename the AsmPrinter directory to InstPrinter for those targets that have 
been MC-ized for assembly printing. MSP430 is mostly so, but still has the
asm printer and lowering code in the printer subdir for the moment.

c14a1eda84 Massive rewrite of MMX: 
The x86_mmx type is used for MMX intrinsics, parameters and
return values where these use MMX registers, and is also
supported in load, store, and bitcast.

Only the above operations generate MMX instructions, and optimizations
do not operate on or produce MMX intrinsics. 

MMX-sized vectors <2 x i32> etc. are lowered to XMM or split into
smaller pieces.  Optimizations may occur on these forms and the
result casted back to x86_mmx, provided the result feeds into a
previous existing x86_mmx operation.

The point of all this is prevent optimizations from introducing
MMX operations, which is unsafe due to the EMMS problem.

45de3f6747 Clean up asm writer usage for x86 and msp430 to flag that the writer should 
use MC instructions in the printInstruction() method via the tablegen flag

480ee577ad Correctly produce R_X86_64_32 or R_X86_64_32S. 
With this patch in

movq    $foo, foo(%rip)
foo:
.long   foo

We produce a R_X86_64_32S for the first relocation and R_X86_64_32 for the
second one.
