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.
