[nvptx] gcc/testsuite/gcc.target/nvptx/

We don't claim to support "K&R C" for nvptx, but needed this corresponding
functionality ("incomplete prototypes") to support the Fortran
libgomp/openacc_lib.h file.

	gcc/testsuite/
	* gcc.target/nvptx/nvptx.exp: New file.
	* gcc.target/nvptx/proto-1.c: Likewise.
