Authentication-results: sourceware.org; auth=none

This is a microoptimisation to call the relevant _M_assign_dispatch
function directly (because we know we have iterators), rather than
calling assign() to do the dispatching.

	* include/bits/stl_list.h (assign(initializer_list<value_type>)): Call
	_M_assign_dispatch directly with correct tag.

Tested powerpc64le-linux, committed to trunk.
