[OpenCL] Add to_{global|local|private} builtin functions. OpenCL builtin functions to_{global|local|private} accepts argument of pointer type to arbitrary pointee type, and return a pointer to the same pointee type in different addr space, i.e. global gentype *to_global(gentype *p); It is not desirable to declare it as global void *to_global(void *); in opencl header file since it misses diagnostics. This patch implements these builtin functions as Clang builtin functions. In the builtin def file they are defined to have signature void*(void*). When handling call expressions, their declarations are re-written to have correct parameter type and return type corresponding to the call argument. In codegen call to addr void *to_addr(void*) is generated with addrcasts or bitcasts to facilitate implementation in builtin library.

Revert "We allow implicit function declarations as an extension in all C dialects. Remove OpenCL special case." Discussed on cfe-commits (Week-of-Mon-20180820), this change leads to the generation of invalid IR for OpenCL without giving an error. Therefore, the conclusion was to revert. llvm-svn: 342885
