Noah Goldstein ba1c3f23d9 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.
