Subject: Define aliases for containers using polymorphic_allocator

These aliases are placed in the top-level header, e.g. <vector> not
<bits/stl_vector.h>. This ensures that they refer to whichever of
std::vector or __debug::vector or __profile::vector is in use when the
header is included.

	* include/std/deque (std::pmr::deque): Declare alias.
	* include/std/forward_list (std::pmr::forward_list): Likewise.
	* include/std/list (std::pmr::list): Likewise.
	* include/std/map (std::pmr::map, std::pmr::multimap): Likewise.
	* include/std/regex (std::pmr::match_results, std::pmr::cmatch)
	(std::pmr::smatch, std::pmr::wcmatch, std::pmr::wsmatch): Likewise.
	* include/std/set (std::pmr::set, std::pmr::multiset): Likewise.
	* include/std/string (std::pmr::basic_string, std::pmr::string)
	(std::pmr::u16string, std::pmr::u32string, std::pmr::wstring):
	Likewise.
	* include/std/unordered_map (std::pmr::unordered_map)
	(std::pmr::unordered_multimap): Likewise.
	* include/std/unordered_set (std::pmr::unordered_set)
	(std::pmr::unordered_multiset): Likewise.
	* include/std/vector (std::pmr::vector): Likewise.
	* testsuite/21_strings/basic_string/types/pmr_typedefs.cc: New test.
	* testsuite/23_containers/deque/types/pmr_typedefs.cc: New test.
	* testsuite/23_containers/forward_list/pmr_typedefs.cc: New test.
