Keith Randall 8dbf3e9393 cmd/compile: fix fuse pass to do CFG surgery correctly
removePred and removeArg do different things. removePred moves the last
predecessor to index k, whereas removeArg slides all the args k or
greater down by 1 index.

Kind of unfortunate different behavior in things named similarly.

Fixes #49122
