[PATCH] Correctly combine alias.scope metadata by a union instead of intersecting
bsteinbr at gmail.com
Sun Feb 8 07:36:35 PST 2015

alias with. When generically combining the metadata from two
instructions the result must be the union of the original sets, because
the new instruction might alias with anything any of the original
instructions aliased with.
