RegisterCoalescer: Fix producing malformed IMPLICIT_DEFs (#73784)
If this was coalescing a SUBREG_TO_REG as a copy, the resulting
instruction would be an IMPLICIT_DEF with an unexpected 2 immediate
operands, which need to be dropped. Until recently the verifier did not
catch this error, and an assert would fire if later the broken
IMPLICIT_DEF was rematerialized P
#73758 is related, it changes the failure mode to a verifier error.
