Fix PR 108582: ICE due to PHI-OPT removing a still in use ssa_name.
This patch adds a check in match_simplify_replacement to make sure the middlebb
does not have any phi-nodes as we don't currently move those.
This was just a thinko from before.
Ok? Bootstrapped and tested on x86_64-linux-gnu with no regressions?
PR tree-optimization/108582
gcc/ChangeLog:
* tree-ssa-phiopt.cc (match_simplify_replacement): Add check
for middlebb to have no phi nodes.
gcc/testsuite/ChangeLog:
* gcc.dg/pr108582-1.c: New test.
