Add Emulate and DumpEmulation to Instruction class.

Move InstructionLLVM out of DisassemblerLLVM class.

Add instruction emulation function calls to SBInstruction and SBInstructionList APIs.

As a result, I had to remove a c++ version of a clang
test which requires more scrutiny on my part.

    Qd -> bit[12] == 0
    Qn -> bit[16] == 0
    Qm -> bit[0]  == 0

If one of these bits is 1, the instruction is UNDEFINED.

It would be better to browse without stylesheet. (eg. on ViewVC)

For register-controlled shifts, we should check that the encoding constraint
Inst{7} = 0 and Inst{4} = 1 is satisfied.

Fix bugs in the pseuo-ization of ADCS/SBCS pointed out by Jim, as well as doing the expansion earlier (using a custom inserter) to allow for the chance of predicating these instructions.

marked explicitly as uninitialized through direct self initialization:

  int x = x;

With r128894 we prevented warnings about this code, and this patch
teaches the analysis engine to continue analyzing subsequent uses of
'x'. This should wrap up PR9624.

There is still an open question of whether we should suppress the
maybe-uninitialized warnings resulting from variables initialized in
this fashion. The definitely-uninitialized uses should always be warned.

When dead code elimination removes all but one use, try to fold the single def into the remaining use.

Rematerialization can leave single-use loads behind that we might as well fold whenever possible.
