 - Pretty messy, but we need to rework how we handle tied operands in MCInst
   anyway.

displacement values.

throughout the X86 encoder.

even for the immediate case.  No functionality change.

same length.

backend to not use exceptions at all except in cases
of actual error.

check in examples cmake list file. This has NOT been tested.

Disassembler to take advantage of the refactored
AsmWriterInst.h.  Note removed parser code.

operand into the CodeGenInstruction's list of operands,
which is useful for EDEmitter.  (Still working on PR6219)

Now that ShrinkDemandedOps() is separated out from DAG combine. It sometimes leave some obvious nops which dag combine used to clean up afterwards e.g. (trunk (ext n)) -> n. Look for them and squash them.

for representing constraint info semantically instead of
as a c expression that will be blatted out to the .inc
file.  Fix X86RecognizableInstr to use this instead of
parsing C code :).

Also, fix a silly memory leak.

register coalescing.  This fixes many crashes and
places where debug info affects codegen (when
dbg.value is lowered to machine instructions, which
it isn't yet in TOT).

The major win of this is that the code is simpler and they 
print on the same line as the instruction again:

        movl    %eax, 96(%esp)          ## 4-byte Spill
        movl    96(%esp), %eax          ## 4-byte Reload
        cmpl    92(%esp), %eax          ## 4-byte Folded Reload

the field from being used uninitialized later in some cases.

OutStreamer.AddBlankLine instead of textually.

IntegerValType holds a uint32_t, so its constructor should take a uint32_t.  This allows it to be properly initialized with bit widths > 65535

prefix which is part of the opcode encoding.

Enhance the x86 backend to show the hex values of immediates in
comments when they are large.  For example:

        movl    $1072693248, 4(%esp)    ## imm = 0x3FF00000

TableGen fragment refactoring.

Move some utility TableGen defs, classes, etc. into a common file so
they may be used my multiple pattern files.  We will use this for
the AVX specification to help with the transition from the current
SSE specification.
