[ARM] Cleanup 64-bit multiplies
Cleanup 64-bit multiplies. Combine the expanders using iterators.
Merge the signed/unsigned multiplies as well as the pre-Armv6 and Armv6
variants. Split DImode operands early into parallel sets inside the
MULL/MLAL instructions - this improves register allocation and avoids
subreg issues due to other DImode operations splitting early.
