[x86_64 PATCH] Update STV's gains for TImode arithmetic right shifts on AVX2.

This patch tweaks timode_scalar_chain::compute_convert_gain to better reflect the expansion of V1TImode arithmetic right shifts by the i386 backend. The comment "see ix86_expand_v1ti_ashiftrt" appears after "case ASHIFTRT" in compute_convert_gain, and the changes below attempt to better match the
