Emit calls to masked_store, not masked_store_blend, when handling masked stores emitted by the frontend. Fix bug in binary8to16 macro in builtins.m4 Fix bug in 16-wide version of __reduce_add_float Remove blend function implementations for masked_store_blend for AVX; just forward those on to the corresponding real masked store functions.
