Don't crash here when we need to add '_' to a parameter list. However,
while we're here, stop trying to emit Fix-Its for implicit
declarations and stop worrying about introducing a ':' after the name
for functions such as
func foo(Int) { ... }
because they're no longer permitted. Fixes rdar://problem/21333445.

If you want to make the parameter and argument label the same in
places where you don't get the argument label for free (i.e., the
first parameter of a function or a parameter of a subscript),
double-up the identifier:
func translate(dx dx: Int, dy: Int) { }
Make this a warning with Fix-Its to ease migration. Part of
rdar://problem/17218256.

Most tests were using %swift or similar substitutions, which did not
include the target triple and SDK. The driver was defaulting to the
host OS. Thus, we could not run the tests when the standard library was
not built for OS X.
