1b91231347 [ARM] In ARMAsmParser, MatchCoprocessorOperandName() permitted p10 and p11 as operands for coprocessor instructions, resulting in encodings that clash with FP/NEON instruction encodings

c19bd32136 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.

c1a91dd97b 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.
