Fix DarwinLdDriverTest.cpp to pass real llvm options.
Fix DarwinLdDriverTest.cpp to pass real llvm options.

After r255819, parse() actually parses what you pass it.

This test was failing because it passed '--debug-only' which isn't in
release builds, but also 'foo' which isn't an option at all.

We now pass -enable-tbaa and -enable-misched which are real options.
