[clang][Darwin] Refactor header search path logic into the driver Summary: This commit moves the logic for determining system, resource and C++ header search paths from CC1 to the driver. This refactor has already been made for several platforms, but Darwin had been left behind. This refactor tries to implement the previous search path logic with perfect accuracy. In particular, the order of all include paths inside CC1 and all paths that were skipped because nonexistent are conserved after the refactor. This change was also tested against a code base of significant size and revealed no problems.
