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. llvm-svn: 184964

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. llvm-svn: 184965

[ARM] In ARMAsmParser, MatchCoprocessorOperandName() permitted p10 and p11 as operands for coprocessor instructions, resulting in encodings that clash with FP/NEON instruction encodings llvm-svn: 194253
