[Darwin Driver] Fix Simulator builtins and test cases

In r339807, I broke linking the builtins libraries for simulator targets, which itself was bad, but turns out it was all completely untested and marked with FIXME in the test suite.

This fixes all the test cases so they actually work, and fixes the bug I introduced in r339807.
