re PR tree-optimization/18291 (ICE in merge_alias_info)

PR tree-optimization/18291
* tree-ssa-copy.c (merge_alias_info): Fix merging of
flow-sensitive alias information.  If the new pointer has no
name tag, copy it from the original pointer.  Otherwise, make
sure that the pointed-to sets have a common intersection.
