Fix missing or incorrect feature test macros 

* doc/xml/manual/status_cxx2017.xml: Document P0032R3 and P0307R2
	status.
	* include/bits/stl_uninitialized.h (__cpp_lib_raw_memory_algorithms):
	Define.
	* include/std/any (__cpp_lib_any): Define as 201606L, because P0032R3
	changes are supported.
	* include/std/optional (__cpp_lib_optional): Likewise.
	* include/std/variant (__cpp_lib_variant): Likewise.
	* include/std/version [!__STRICT_ANSI__]
	(__cpp_lib_uncaught_exceptions): Define as long integer.
	[__cplusplus >= 201703L] (__cpp_lib_any)
	(__cpp_lib_raw_memory_algorithms, __cpp_lib_uncaught_exceptions)
	(__cpp_lib_variant): Define for C++17.
	[__cplusplus >= 201703L] (__cpp_lib_optional): Update value and define
	as long integer.
	* libsupc++/exception (__cpp_lib_uncaught_exceptions): Define as long
	integer.
