tree-optimization/100278 - handle mismatched code in TBAA adjust of PRE
PRE has code to adjust TBAA behavior for refs that expects the base
operation code to match. The testcase shows a case where we have
a VAR_DECL vs. a MEM_REF so add code to give up in such cases.

* tree-ssa-pre.c (compute_avail): Give up when we cannot
adjust TBAA beacuse of mismatching bases.
* gcc.dg/tree-ssa/pr100278.c: New testcase.
