Optimize locale::_M_impl->_M_names for the most common cases:
!_M_names[0] means unnamed; !_M_names[1] means all the categories
the same name (_M_names[0] && _M_names[1] means that the full set
of _M_names must be processed, the general case).
* include/bits/locale_classes.h (locale::_Impl::_M_check_same_name):
Tweak, saving work when !_M_names[1].
(locale::locale(const locale&, _Facet*): Simplify: now just setting
_M_names[0] = 0 means unnamed.
* src/locale.cc (locale::operator==): Deal first with the common,
easy cases, otherwise fall back to locale::name().
(locale::name()): Tweak, if !_M_names[0] just return "*".
(locale::_Impl::_Impl(const _Impl&, size_t): Tweak, early stop
copying __imp._M_names if !__imp._M_names[0] or !__imp._M_names[1].
* src/locale_init.cc (locale::_Impl::_Impl(size_t)): Tweak.
* src/localename.cc (locale::_Impl::_Impl(const char*, size_t):
Simplify when !std::strchr, just updating _M_names[0]; clean up.
(locale::_Impl::_M_replace_categories): When !_M_names[1] prepare
for the general case (full set of names), then do the usual work;
clean up.
* src/locale.cc (locale::name()): Reserve space in __ret.
* src/locale_init.cc (locale::global(const locale&)): Save
the name in a temporary.
* src/localename.cc (locale::locale(const char*)): Reserve space
in __str.

avoiding reallocation for common case.

streamsize, char_type)): Use traits::find/copy in a loop to speed
up greatly the function in the common case (I/O buffer size >> 1).

* include/bits/istream.tcc (getline(basic_istream<>&,
basic_string<>&, _CharT)): Change to use sgetc()/snextc() instead
of sbumpc(), consistently with the other functions, thus also
dealing correctly with the case of exceeded string::max_size().
