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.

The names of actual arguments are checked at resolving time
for a mismatch instead of deferring this check to the function
prologue (emitted as part of the CopyParameters() prologue).
For example:
class A {
foo({a:42}) => null;
}
main() {
var a = new A();
a.foo(b:123); // noSuchMethod: no named parameter named "b".
}
This enables e.g. fast noSuchMethod invocation in the case
of a named argument mismatch.
It also makes the function prologue for instance functions that
use optional parameters shorter by omitting the check for a
name mismatch there.
