ARM: Let the assembler reject v5 instructions in v4 mode. PR18524. llvm-svn: 199559

[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.

[ARM] ARM mov InstAlias for MOVW lacks HasV6T2 The movw instruction is only available in ARM state for V6T2 and above. The MOVi16 instruction has requirement HasV6T2 but the InstAlias for mov rd, imm where the operand is imm0_65535_expr:$imm does not. This means that movw can incorrectly be used in ARMv4 and ARMv5 by writing mov rd, 0x1234. The simple fix is to the requirement HasV6T2 to the InstAlias. Tests added to not-armv4.s. Patch by Peter Smith. llvm-svn: 269761
