Certain backends, e.g. NVPTX, do not support '.' in function names. Hence, we ensure all '.' are replaced by '_' when generating function names for subfunctions. For the current OpenMP code generation, this is not strictly necessary, but future uses cases (e.g. GPU offloading) need this issue to be fixed. llvm-svn: 246980
