Various AVX fixes (found by inspection).

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.
