pointer and length, and allocate the arrays in ScalarEvolution's
BumpPtrAllocator, so that they get released when their owning
SCEV gets released. SCEVs are immutable, so they don't need to worry
about operand array resizing. This fixes a memory leak reported
in PR6637.

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]

libstdc++'s std::string class points to the interior of an allocation, valgrind
reports strings still alive at program termination as possible leaks. I didn't
use a ManagedStatic for this because System can't depend on Support.

optional register update argument, which is currently unused -- when we add
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,

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.
