Subject: [PATCH] libgomp testsuite: Localize 'lang_[...]' etc.

..., instead of letting them bleed into the next '*.exp' file, requiring
clean-up there.

	libgomp/
	* testsuite/libgomp.c++/c++.exp: Localize 'lang_[...]' etc.
	* testsuite/libgomp.c/c.exp: Likewise.
	* testsuite/libgomp.fortran/fortran.exp: Likewise.
	* testsuite/libgomp.graphite/graphite.exp: Likewise.
	* testsuite/libgomp.oacc-c++/c++.exp: Likewise.
	* testsuite/libgomp.oacc-c/c.exp: Likewise.
	* testsuite/libgomp.oacc-fortran/fortran.exp: Likewise.
