[PATCH] D49486: [cfe][CMake] Export the clang resource directory

Out-of-tree tools trying to parse source files need the builtin headers
such as `stddef.h`. If the tool isn't installed together with clang, it
can't find them automatically. Exporting the location makes this much
easier.

(Resubmitting because I've subscribed the wrong list, sorry for the noise).
