This patch adds a `-fdeclare-opencl-builtins` command line option to the clang frontend. This enables clang to verify OpenCL C builtin function declarations using a fast StringMatcher lookup, instead of including the opencl-c.h file with the `-finclude-default-header` option. This avoids the large parse time penalty of the header file. This commit only adds the basic infrastructure and some of the OpenCL builtins. It does not cover all builtins defined by the various OpenCL specifications. As such, it is not a replacement for `-finclude-default-header` yet.
