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.

This fixes bugs when we call the result of generic methods that return functions; we were advancing through orig types of the signature but not formal ones, causing us to fall out of sync when we exhausted curry levels of the original function and started calling function-typed results. Fixes rdar://problem/18143223 and rdar://problem/18495979, maybe others too.
