The attached patch determines what path prefix gcc would use for gcov
coverage data files and puts is in a cc1 flag -coverage-dir which is
threaded into codegen who finally plops it in a metadata node.
The point of putting it in metadata is to allow us to produce a .bc
file and still get the same behaviour as when we go straight to .o
file, and this also will work when we merge .bc files and then run the
-insert-gcov-profiling pass.
It's a small patch. Please review!
