Fuzz testing identified a lowering case for CLIF's `icmp` in which the double use of a loaded operand resulted in a register allocation error. This change manually adds `put_in_xmm` to avoid load-coalescing these values and includes a CLIF filetest to trigger this issue. Closes #3951. I opened #3953 to discuss a way in which this kind of mistake (i.e., forgetting to add `put_in_*` in certain situations) could be avoided.
