Jonathan Wakely 61f5cb2313 PR libstdc++/89164 enforce constraints for uninitialized algos
The memmove optimizations for std::uninitialized_copy/fill/_n will
compile even if the type is not copy constructible, because std::copy
doesn't require copy construction to work. But the uninitialized
algorithms do require it.

This adds explicit static assertions to ensure we don't allow ill-formed
initializations.

	PR libstdc++/89164
	* include/bits/stl_algobase.h (__copy_move): Give descriptive names
	to template parameters.
	* include/bits/stl_uninitialized.h (uninitialized_copy)
