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.

ba2ac80921 ARM encodes Q registers as 2xregno (i.e. the number of the D register that corresponds to the lower 
half of the Q register), rather than with just regno.  This allows us to unify the encodings for
a lot of different NEON instrucitons that differ only in whether they have Q or D register operands.

8a77999240 Adding initial AsmParser implementation for the MBlaze backend. It is 
mostly based on the ARM AsmParser at this time and is not particularly
functional.

Changed the MBlaze data layout from:
    "E-p:32:32-i8:8:8-i16:16:16-i64:32:32-f64:32:32-v64:32:32-v128:32:32-n32"
to:
    "E-p:32:32:32-i8:8:8-i16:16:16"
because the MicroBlaze doesn't have i64, f64, v64, or v128 data types.

Cleaned up the MBlaze source code:
    1. The floating point register class has been removed. The
       MicroBlaze does not have floating point registers. Floating
       point values are simply stored in integer registers.
    2. Renaming the CPURegs register class to GPR to reflect the
       standard naming.
    3. Removing a lot of stale code from AsmPrinter after
       the conversion to InstPrinter.
    4. Simplified sign extended loads by marking them as
       expanded in ISelLowering.

b15029ea7e More load/store refactoring, call reg+offset simplification from within 
the emitter to handle the addresses. Only simplify the offset if we need
to - also fix bug where in addrmode 5 we weren't dividing the offset by
4, which showed up due to not always lowering.

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.
