Making these non-templates will allow them to be moved into the library
at some point.
libstdc++-v3/ChangeLog:
* include/bits/atomic_wait.h (__platform_wait): Change function
template to a normal function. The parameter is always
__platform_wait_t* which is just int* for this implementation of
the function.
(__platform_notify): Likewise.
