tree-optimization/108821 - store motion and volatiles
The following fixes store motion to not re-issue volatile stores
to preserve TBAA behavior since that will result in the number
of volatile accesses changing.
PR tree-optimization/108821
* tree-ssa-loop-im.cc (sm_seq_valid_bb): We can also not
move volatile accesses.
* gcc.dg/tree-ssa/ssa-lim-24.c: New testcase.
