d03783eaf2 the immediate field of pshufw is actually an 8-bit field, not a 8-bit field that is sign extended. This fixes PR8288

4599fd89fd add support for the prefetch/prefetchw instructions, move femms into 
the right file.  The assembler supports all the 3dnow instructions now,
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.

3c29a2b776 fix a regression introduced in r115243, in which the instruction 
backing int_x86_ssse3_pshuf_w got removed.  This caused PR8280.

5aae0d6863 Factor some logic into ShouldRelocOnSymbol. This simplifies the code and 
fixes some cases where we were producing relocations with at symbol that
should use a section instead.

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.

3e2630deca Make it possible for the MCObjectWriter to decide if a given fixup is fully 
resolved or not. Different object files have different restrictions and
different native assemblers have different idiosyncrasies we want to emulate
for now.

Move the existing MachO logic to the new place and implement an ELF one that
gets fixups to globals right.

c14d59589c add basic avx support to the disassembler, also teach it about ssmem/sdmem 
operands.

With this done, we can remove the _Int suffixes from the round instructions
without the disassembler blowing up.  This allows the assembler to support
them, implementing rdar://8456376 - llvm-mc rejects 'roundss'
