support for that, it can just be a separate operand.

This is for the disassembly work.

There are cases where this is not possible, for example, A8.6.53 LDM Encoding T1.
In such case, we'll use an adhoc approach to deduce the Opcode programmatically.

(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.
