tree-optimization/89317 - missed folding of (p + 4) - &p->d
The PR notices we fail to simplify
a_4 = &x_3(D)->data;
b_5 = x_3(D) + 16;
_1 = b_5 - a_4;
together with the enabler handling ADDR_EXPR leafs in separate
stmts in match.pd the suggested patterns work.
PR tree-optimization/89317
* match.pd ((p + b) - &p->c -> b - offsetof(c)): New patterns.
* gcc.dg/tree-ssa/pr89317.c: New testcase.
