(RISCDisassemblerEmitter) which emits the decoder functions for ARM and Thumb,
and the disassembler core which invokes the decoder function and builds up the
MCInst based on the decoded Opcode.

Added sub-formats to the NeonI/NeonXI instructions to further refine the NEONFrm
instructions to help disassembly.

We also changed the output of the addressing modes to omit the '+' from the
assembler syntax #+/-<imm> or +/-<Rm>.  See, for example, A8.6.57/58/60.

And modified test cases to not expect '+' in +reg or #+num.  For example,

; CHECK:       ldr.w	r9, [r7, #28]

This does not move entirely to UAL syntax, since the default "increment after"
suffix is empty but we still use "IA" for that.

adjusted unittest

I have added some doxygen to OptionalOperandTraits,
so hopefully there will be no confusion in the future.

Incidentally OptionalOperandTraits is not used any more (IIUC),
but the obvious client would be BranchInstr, and I plan
to rearrange it that way.

This uses llc with the integrated assembler as the test compiler and llc
without it as the safe compiler.

to LLVM IR changes with addr label weirdness.  In the testcase, we
generate references to the two bb's when codegen'ing the first
function:

_test1:                                 ## @test1
	leaq	Ltmp0(%rip), %rax
..
	leaq	Ltmp1(%rip), %rax

Then continue to codegen the second function where the blocks
get merged.  We're now smart enough to emit both labels, producing
this code:

_test_fun:                              ## @test_fun
## BB#0:                                ## %entry
Ltmp1:                                  ## Block address taken
Ltmp0:
## BB#1:                                ## %ret
	movl	$-1, %eax
	ret

Rejoice.

 - Although it would be nice to allow this decoupling, the assembler needs to be able to reason about MCSymbolRefExprs in too many places to make this viable. We can use a target specific encoding of the variant if this becomes an issue.
 - This patch also extends llvm-mc to support parsing of the modifiers, as opposed to lumping them in with the symbol.

when all indices are needed, just store the input vector to the stack and
load the elements out.

label is generated, but then the block is deleted.  Since the
value is undefined, we just emit the label right after the entry 
label of the function.  It might matter that the label is in the
same section as the function was afterall.
