The condition checks that the two BBs share the same successor but forgot to
check that both BB have only one successor.
It looks like with -m32 (and powerpc) the order of the edges just happen to
match and the assert triggers.
Testing a patch overnight and will post tomorrow.

middle-end: Fix phi-ssa assertion triggers. [PR106519]
For the diamond PHI form in tree_ssa_phiopt_worker we need to
extract edge e2 sooner. This changes it so we extract it at the
same time we determine we have a diamond shape.
gcc/ChangeLog:
PR middle-end/106519
* tree-ssa-phiopt.cc (tree_ssa_phiopt_worker): Check final phi edge
for
diamond shapes.
gcc/testsuite/ChangeLog:
PR middle-end/106519
* gcc.dg/pr106519.c: New test.

Yes, should be, tested the x86 -m32 failures but the other arches should be the
same.
