libstdc++: Refactor std::call_once internals
This separates the definition of std::__call_proxy into two funcions,
one for TLS and one for non-TLS, to make them easier to read. It also
replaces the __get_once_functor_lock_ptr() internal helper with a new
set_lock_ptr(unique_lock<mutex>*) function so that __once_proxy doesn't
need to call it twice.
libstdc++-v3/ChangeLog:
* src/c++11/mutex.cc [_GLIBCXX_HAVE_TLS] (__once_proxy): Define
separately for TLS targets.
[!_GLIBCXX_HAVE_TLS] (__get_once_functor_lock_ptr): Replace with ...
(set_lock_ptr): ... this. Set new value and return previous
value.
[!_GLIBCXX_HAVE_TLS] (__set_once_functor_lock_ptr): Adjust to
use set_lock_ptr.
[!_GLIBCXX_HAVE_TLS] (__once_proxy): Likewise.
