Chandler Carruth 582b2c04dd Allow GoogleTest tests to locate their executable path. (#3992)
This also factors out the code for doing this location from the driver
to a tiny helper library.

The motivation for this is letting tests locate data files like the
prelude or other files needed by the toolchain more easily. A subsequent
PR will use this heavily in the Clang runner and related logic for
example.
