Improve ARM assembly parsing diagnostics a bit. Catch potential cascading errors on a malformed so_reg operand and bail after the first error. Add some tests for the diagnostics we do want. llvm-svn: 135055

@ Check for various assembly diagnostic messages on invalid input.
ARM diagnostic when 's' suffix on mnemonic that can't set flags. For example, "mlss r0, r1, r2, r3". The MLS instruction does not have a flag-setting variant. llvm-svn: 135203

ARM assembly parsing for MOV (immediate). Add range checking for the immediate operand and handle the "mov" mnemonic choosing between encodings based on the value of the immediate. Add tests for fixups, encoding choice and values, and diagnostic for out of range values. llvm-svn: 135500

ARM assembly parsing and encoding for SSAT instruction. Fix the Rn register encoding for both SSAT and USAT.
