Varargs methods are problematic

[GoogleCodeExporter]

Varargs methods are problematic: we're taking foo(arg1, arg2, vargs) and
turning it into RT.invoke(recv, name, vargs) which necessitates
re-resolving the matching vararg method at runtime (currently with no
static type information).

Maybe all of this can be circumvented by not invoking methods reflectively
when they successfully resolve.

We need to avoid passing array as sole final argument to RT.invoke and
RT.invokeStatic, can happen when passing an argument in an untransformed
method and for literals:
  * main(String[] args) { foo(args); }
  * foo(new String[] { ... })
