Artyom Skrobov 8653443902 [ARM] In ARMAsmParser, MatchCoprocessorOperandName() permitted p10 and p11 as operands for coprocessor instructions, resulting in encodings that clash with FP/NEON instruction encodings

Tim Northover 2c45a383a8 ARM: fix more cases where predication may or may not be allowed
Unfortunately this addresses two issues (by the time I'd disentangled the logic
it wasn't worth putting it back to half-broken):

+ Coprocessor instructions should all be predicable in Thumb mode.
+ BKPT should never be predicable.

Tim Northover 52f77f5cda ARM: allow predicated barriers in Thumb mode
The barrier instructions are only "always-execute" in ARM mode, they can quite
happily sit inside an IT block in Thumb.
