regalloc: optimize a little edge case better
With two-address instructions one needs to make sure the dst doesn't get
allocated to the same reg as the right-hand operand:
%r = mul %x, %y ; %y cannot be %r
Except, if the operands are the same
%r = mul %x, %x ; if %x is dead after this instr, it's fine to
allocate %r to the same reg
