Log:
ifcvt: Call fixup_partitions (PR83361)

After converting a conditional branch to an unconditional trap to a
conditional trap, if the original trap is still reachable from another
path, it may be that it is in a hot basic block  and only reachable from
cold blocks.  Fix that up.

	* ifcvt.c (if_convert): Call fixup_partitions.
