libstdc++: Add always_inline to trivial iterator operations
libstdc++-v3/ChangeLog:
* include/bits/stl_iterator_base_funcs.h (__distance):
Add always_inline attribute to overload for random
access iterators.
(advance, distance, next, prev): Add always_inline attribute to
inline functions that just forward to another function.
