89df996ab2 Thumb2 assembler parsing and encoding of IT instruction.
This handles only the handling of the IT instruction itself, not the
processing and validation of the instructions in the IT block. That's next,
and will include encoding tests for IT itself.

9ab0f25fc1 invalid-LDR_PRE-arm.txt was already passing, but for the wrong reasons. We were failing to specify enough fixed bits of LDR_PRE/LDRB_PRE, resulting in decoding conflicts. Separate them into immediate vs. register versions, allowing us to specify the necessary fixed bits. This in turn results in the test being decoded properly, and being rejected as UNPREDICTABLE rather than a hard failure.

We'll need to pay attention to them when we start getting more serious about
the details of parsing thumb2 assembly.

70939ee141 ARM clean up the imm_sr operand class representation.

thumb shift instructions.

47a0d52b69 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.
