First step to allowing the resource directory of Clang to be adjusted for

strange packaging environments. The primary result of this is to expose
a (normally empty) CLANG_RESOURCE_DIR string in the autoconf and CMake builds.
This will in turn be used by a subsequent commit to Clang.

Regenerated configure and config.h.in thanks to Nick. =D
