b9e8700beb Reverting r117031 to cleanup valgrind errors. 
It doesn't look like anything is wrong with the checkin,
but the new test cases expose a mem bug in AsmParser.

9a40554de4 Fixed handling of immediate operand sizes, which 
weren't properly reflecting the OperandSize attribute
of the instruction leading to improper decoding of
certain instructions with the 66H prefix.  Also added
a test case for this.

c63105a064 More tweaks to X86 instructions to allow the 'w' suffix in places it makes 
sense, when the instruction takes the 16-bit ax register or m16 memory
location.  These changes to llvm-mc matches what the darwin assembler allows
for these instructions.  Also added the missing flex (without the wait prefix)
and ud2a as an alias to ud2 (still to add ud2b).

3478e641b9 Reverting the commit 116986. It was breaking the build on llvm-x86_64-linux though it

again.

c50372298d Major update of the MicroBlaze backend. The new features are: 
1. A delay slot filler that searches for valid instructions
       to fill the delay slot with. Previously NOPs would always
       be inserted into delay slots.
    2. Support for MC based instruction printer added.
    3. Support for MC based machine code generation and ELF
       file generation. ELF file generation does not yet
       completely work as much of the ELF support infrastructure
       is still x86/x86-64 specific.
    4. General clean up of the MBlaze backend code. Much of the
       tablegen code has been cleanup and simplified.

Bug Fixes:
    1. Removed duplicate periods from subtarget feature descriptions.
    2. Many of the instructions had bad machine code information
       in the tablegen files. Much of this has been fixed.

9a06e4c7c8 More accurate estimate / tracking of register pressure. 
- Initial register pressure in the loop should be all the live defs into the
  loop. Not just those from loop preheader which is often empty.
- When an instruction is hoisted, update register pressure from loop preheader
  to the original BB.
- Treat only use of a virtual register as kill since the code is still SSA.

erased the instruction during LICM so UpdateRegPressureAfter() should not
reference it afterwards.

ccbc75257a Fixing r116753 r116756 r116777 
The failures in r116753 r116756 were caused by a python issue -
Python likes to append 'L' suffix to stringified numbers if the number
is larger than a machine int. Unfortunately, this causes a divergence of
behavior between 32 and 64 bit python versions.

I re-crafted elf-dump/common_dump to take care of these issues by:

1. always printing 0x (makes for easy sed/regex)
2. always print fixed length (exactly 2 + numBits/4 digits long)
   by mod ((2^numBits) - 1)
3. left-padded with '0'

There is a residual common routine that is also used by
macho-dump (dataToHex) , so I left the 'section_data' test values alone.
