Jim Grosbach 838ed3af46 Thumb .n mnemonic qualifiers can be ignored for now.
We'll need to pay attention to them when we start getting more serious about
the details of parsing thumb2 assembly.

Jim Grosbach 4b701af908 Thumb parsing and encoding for SUB (SP minu immediate).
Fix FiXME in test file. Remove FIXME for SUB (SP minus register) since that
form is Thumb2 only.

Jim Grosbach 0a0b3071df Thumb parsing and encoding support for ADD SP instructions.
Fix the test FIXME and add parsing support for the ADD (SP plus immediate)
and ADD (SP plus register) instruction forms.

Jim Grosbach 90103ccc05 Thumb assembly parsing and encoding for LDM instruction.
Fix base register type and canonicallize to the "ldm" spelling rather than
"ldmia." Add diagnostics for incorrect writeback token and out-of-range
registers.

Jim Grosbach 46dd413991 ARM clean up the imm_sr operand class representation.
Represent the operand value as it will be encoded in the instruction. This
allows removing the specialized encoder and decoder methods entirely. Add
an assembler match class while we're at it to lay groundwork for parsing the
thumb shift instructions.

Jim Grosbach 3e941aee69 ARM thumb assembly parsing for arithmetic flag setting instructions.
Thumb one requires that many arithmetic instruction forms have an 'S'
suffix. For Thumb2, the whether the suffix is required or precluded depends
on whether the instruction is in an IT block. Use target parser predicates
to check for these sorts of context-sensitive constraints.

Jim Grosbach 120a96a721 MCTargetAsmParser target match predicate support.
Allow a target assembly parser to do context sensitive constraint checking
on a potential instruction match. This will be used, for example, to handle
Thumb2 IT block parsing.

Jim Grosbach 27ad83d8a9 ARM push of a single register encodes as pre-indexed STR.
Per the ARM ARM, a 'push' of a single register encodes as an STR,
not an STM.

not an LDM.
