arc: Detect usage of illegal double register pairs
ARC can use odd-even double register pairs in some selected
instructions. Although the GNU assembler doesn't allow even-odd
registers to be used, there may be cases when the disassembler is
presented with such situation. This patch add a test and detects such
cases.
