Update VM to latest spec. Referencing a name that is imported from more than one library is no longer a compile-time error. If one of the sources of an ambiguous reference is a dart library, the dart library declaration is automatically hidden. Also fixes a bug where looking up a getter name in a library found the getter even though the name is filtered out in the 'hide' combinator. Long-term we should fix the need for repeatedly convert between the mangled getter and setter names and the untangled name. Fixes 12915, 12913, 12724.
