[turbofan] Use register for instruction operands when SameAsFirst is specified.

As the register allocator cannot reuse spill slots, SameAsFirst
constraint means that we would have to do an expensive move to a
differen spill slot if we choose to spill. Forcing the operand
to a register is cheaper.

In zlib, we get >10% speed-up for ia32, >25% for x64.
