	* config/locale/gnu/codecvt_members.cc (codecvt::do_in):
	Rewrite, using both mbsnrtowcs and mbrtowc in a loop: the
	former is very fast, but stops if encounters a NUL.
	(codecvt::do_out): Tweak.
	* testsuite/performance/wchar_t_in.cc: New.

	* include/bits/locale_facets.h
	(__numpunct_cache<>::_M_cache): Set _M_allocated at the beginning
	in order to avoid memory leaks; simplify a bit.
