create_testsuite_files: Add testsuite/experimental in the list of folders to search for tests.

2014-01-20  François Dumont  <fdumont@gcc.gnu.org>

	* scripts/create_testsuite_files: Add testsuite/experimental in
	the list of folders to search for tests.
	* include/experimental/string_view
	(basic_string_view<>::operator[]): Comment _GLIBCXX_DEBUG_ASSERT,
	incompatible with constexpr qualifier.
	(basic_string_view<>::front()): Likewise.
	(basic_string_view<>::back()): Likewise.
	* testsuite/experimental/string_view/element_access/wchar_t/2.cc:
	Merge dg-options directives into one.
	* testsuite/experimental/string_view/element_access/char/2.cc:
	Likewise. Remove invalid experimental namespace scope on
	string_view_type.
