PR tree-optimization/88775
* match.pd (cmp (convert1?@2 addr@0) (convert2? addr@1)): Optimize
equal == 0 equality pointer comparisons some more if compared in
integral types and either one points to an automatic var and the
other to a global, or we can prove at least one points to the middle
or both point to start or both point to end.
* gcc.dg/tree-ssa/pr88775-1.c: New test.
* gcc.dg/tree-ssa/pr88775-2.c: New test.
