Peter Klausler 4ad7279392 [flang] CUDA Fortran - part 1/5: parsing ... Begin upstreaming of CUDA Fortran support in LLVM Flang. This first patch implements parsing for CUDA Fortran syntax, including: - a new LanguageFeature enum value for CUDA Fortran - driver change to enable that feature for *.cuf and *.CUF source files - parse tree representation of CUDA Fortran syntax - dumping and unparsing of the parse tree - the actual parsers for CUDA Fortran syntax - prescanning support for !@CUF and !$CUF - basic sanity testing via unparsing and parse tree dumps ... along with any minimized changes elsewhere to make these work, mostly no-op cases in common::visitors instances in semantics and lowering to allow them to compile in the face of new types in variant<> instances in the parse tree. Because CUDA Fortran allows the kernel launch chevron syntax ("call foo<<<blocks, threads>>>()") only on CALL statements and not on function references, the parse tree nodes for CallStmt, FunctionReference, and their shared Call were rearranged a bit; this caused a fair amount of one-line changes in many files. More patches will follow that implement CUDA Fortran in the symbol table and name resolution, and then semantic checking.
