7e99a60857 ARM: Define generic HINT instruction. 
The NOP, WFE, WFI, SEV and YIELD instructions are all hints w/
a different immediate value in bits [7,0]. Define a generic HINT
instruction and refactor NOP, WFI, WFI, SEV and YIELD to be
assembly aliases of that.

54319e2a8c ARM: Add a few missing add->sub aliases w/ 'w' suffix. 
Aliases for adding a negative immediate when using an explicit 'w'
suffix. E.g.,
        adds.w r2, #-16
        adds.w r2, r2, #-16
        addw r2, #-16
        addw r2, #-16
        addw r2, r2, #-16

a9cc08f24f ARM: Thumb add(sp plus register) asm constraints. 
Make sure when parsing the Thumb1 sp+register ADD instruction that
the source and destination operands match. In thumb2, just use the
wide encoding if they don't. In Thumb1, issue a diagnostic.

a23ecc2ba9 ARM fix cc_out operand handling for t2SUBrr instructions. 
We were incorrectly conflating some add variants which don't have a
cc_out operand with the mirroring sub encodings, which do. Part of the
awesome non-orthogonality legacy of thumb1. Similarly, handling of
add/sub of an immediate was sometimes incorrectly removing the cc_out
operand for add/sub register variants.

ad353c6303 ARM assembler should prefer non-aliases encoding of cmp. 
When an immediate is both a value [t2_]so_imm and a [t2_]so_imm_neg,
we want to use the non-negated form to make sure we prefer the normal
encoding, not the aliased encoding via the negation of, e.g., 'cmp.w'.

2d30d947ec ARM integrated assembler should encoding choice for add/sub imm. 
For 'adds r2, r2, #56' outside of an IT block, the 16-bit encoding T2
can be used for this syntax. Prefer the narrow encoding when possible.

8d11c6349f ARM/Thumb2 'cmp rn, #imm' alias to cmn. 
When 'cmp rn #imm' doesn't match due to the immediate not being representable,
but 'cmn rn, #-imm' does match, use the latter in place of the former, as
it's equivalent.

5d0492cfc4 Thumb2 ADD/SUB instructions encoding selection outside IT block. 
Outside an IT block, "add r3, #2" should select a 32-bit wide encoding
rather than generating an error indicating the 16-bit encoding is only
legal in an IT block (outside, the 'S' suffic is required for the 16-bit
encoding).
