x86: Cleanup bounds checking in large memcpy case
1. Fix incorrect lower-bound threshold in L(large_memcpy_2x). Previously was using `__x86_rep_movsb_threshold` and should have been using `__x86_shared_non_temporal_threshold`. 2. Avoid reloading __x86_shared_non_temporal_threshold before the L(large_memcpy_4x) bounds check. 3. Document the second bounds check for L(large_memcpy_4x) more clearly.
