re PR tree-optimization/19121 (ICE: in merge_alias_info, at tree-ssa-copy.c:236)
PR tree-optimization/19121
* tree-ssa-alias.c (compute_flow_sensitive_aliasing): When
adding aliases to a name tag, also add them to the pointer's
type tag.
* tree-ssa-copy.c (merge_alias_info): Do not merge flow
sensitive alias info at all. Only check that the two pointers
have compatible pointed-to sets.
* tree-ssa.c (verify_name_tags): Verify that the alias set of
a pointer's type tag is a superset of the alias set of the
pointer's name tag.
