8d8cb5c491 Fixed the SS42AI template for the SSE 4.2 instructions with TA prefix so it does 
not get an "Unknown immediate size" assert failure when used.  All instructions 
of this form have an 8-bit immediate.  Also added a test case of an example
instruction that is of this form.

97cf61ad35 MC/Mach-O: Tweak optimal_nop test to be host independent. 
- This also avoids us running valgrind on /usr/bin/as, which has leaks. :)

766909ae3b Fixed the encoding problems of the crc32 instructions. All had the Operand size 
override prefix and only the r/m16 forms should have had that.  Also for variant
one, the AT&T syntax, added suffixes to all forms.  Also added the missing
64-bit form for 'CRC32 r64, r/m8'.  Plus added test cases for all forms and
tweaked one test case to add the needed suffixes.

3c66c7a3c1 MC/Mach-O/x86_64: Add relocation support. 
- This is "extraordinarily" Darwin 'as' compatible. See the litany of FIXMEs littered about for more information.
 - There are a few cases which seem to clearly be 'as' bugs which I have left unsupported, and there is one cases where we diverge but should fix if it blocks diffing .o files (Darwin 'as' ends up widening a jump unnecessarily).
 - 403.gcc build, runs, and diffs equivalently to the 'as' built version now (using llvm-mc). However, it builds so slowly that I wouldn't recommend trying it quite yet. :)

ab14df376a MC/X86/AsmMatcher: Use the new instruction cleanup routine to implement a 
temporary workaround for matching inc/dec on x86_64 to the correct instruction.
 - This hack will eventually be replaced with a robust mechanism for handling
   matching instructions based on the available target features.

e8b67adb94 MC/Mach-O: PCrel relocations weren't using the right base address, they are 
relative to the fragment address, not its offset. This was masked by the text
section normally being at address 0.

8ad9589475 MC/Mach-O: Implement initial support for relaxation. 
- The implementation is currently very brain dead and inefficient, but I have a
   clear plan on how to fix it.

 - The good news is, it works and correctly assembles 403.gcc (when built with
   Clang, at '-Os', '-Os -g', and '-O3'). Even better, at '-Os' and '-Os -g',
   the resulting binary is exactly equivalent to that when built with the system
   assembler. So it probably works! :)

11cce486ac This is a patch to the assembler frontend to detect when aligning a text 
section with TextAlignFillValue and calls EmitCodeAlignment() instead of
calling EmitValueToAlignment().  This allows x86 assembly code to be aligned
with optimal nops.

9be8c4c590 Replace this file containing 4 tests of x86 32-bit encodings with a file 
containing the subset of the full auto generated test case that currently
encodes correctly.  Again it is useful as we bring up the the new encoder
to make sure currently working stuff stays working.
