lrn@google.com 53dc9ba034 Change the field and constructor parameter types of NoSuchMethodError to Symbol.
The NSME uses strings for names. It should use symbols.

This change modifies the VM libraries only enough to make the signature change
not crash. It will probably need cleanup to ensure that symbols are passed
to the internal constructor directly, instead of strings that have to be
converted.

(Also fixes a type error in Map.fromIterable that was hit by the code).
