PR tree-optimization/19831
* tree-ssa-dce.c (propagate_necessity): Calls to functions
that only act as barriers do not make any previous stores
necessary.
* tree-ssa-structalias.c (handle_lhs_call): Delay making
HEAP variables global, do not add a constraint from nonlocal.
(find_func_aliases): Handle escapes through return statements.
(compute_points_to_sets): Make escaped HEAP variables global.
* gcc.dg/tree-ssa/20041122-1.c: Enable TBAA, scan FRE dump,
make allocated memory escape. Un-XFAIL.
* gcc.dg/vect/pr21591.c: Make allocated memory escape.
* gcc.dg/vect/pr31699.c: Likewise.
