Keith Randall 9088c691da cmd/compile: ensure temp register mask isn't empty
We need to avoid nospill registers at this point in regalloc.
Make sure that we don't restrict our register set to avoid registers
desired by other instructions, if the resulting set includes only
nospill registers.

Fixes #57846
