Fix BXJ is undefined in AArch32. BXJ was incorrectly said to be unsupported in ARMv8-A. It is not supported in the A64 instruction set, but it is supported in the T32 and A32 instruction sets, because it's listed as an instruction in the ARM ARM section F7.1.28. Using SP as an operand to BXJ changed from UNPREDICTABLE to PREDICTABLE in v8-A. This patch reflects that update as well. This was found by MCHammer. llvm-svn: 235024

@ UNDEF: error: r13 (SP) is an unpredictable operand to BXJ
[ARM] Use new assembler diags for ARM This converts the ARM AsmParser to use the new assembly matcher error reporting mechanism, which allows errors to be reported for multiple instruction encodings when it is ambiguous which one the user intended to use. By itself this doesn't improve many error messages, because we don't have diagnostic text for most operand types, but as we add that then this will allow more of those diagnostic strings to be used when they are relevant.
