* tree-ssa-copy.c (may_propagate_copy): Remove redundant
checks.
(merge_alias_info): Do verification only if checking is
enabled.  Merge flow-sensitive alias information in simple
cases.
* tree-ssa-operands.c (get_addr_dereference_operands): Also
complain about missing NMTs.

* gcc.dg/tree-ssa/alias-17.c: New testcase.
