libstdc++: Fix -Wsign-compare warnings in headers
libstdc++-v3/ChangeLog:
* include/bits/locale_conv.h (__str_codecvt_out_all):
Add cast to compare operands of the same signedness.
* include/bits/locale_facets_nonio.tcc
(time_get::_M_extract_wday_or_month): Likewise.
* include/bits/sstream.tcc (basic_stringbuf::overflow):
Likewise.
* include/tr1/legendre_function.tcc (__sph_legendre): Use
unsigned for loop variable.
