  The following three patches further enhance loongarch’s vectorization capabilities.

Patch one add LoongArch support for AVG_CEIL/FLOOR.

Patch 2 add LoongArch support for vec_widen_mult/add/sub_lo/hi patterns.

patch 3 make loongarch use the new vector hooks and implements the costing
function determine_suggested_unroll_factor, to make it be able to suggest the
unroll factor for a given loop being vectorized base vec_ops analysis during
vector costing and the available issue information.The patch also adjusts cost
model through performance analysis.

Jiahao Xu (3):
  LoongArch:Implement avg and sad standard names.
  LoongArch:Implement vec_widen standard names.
  LoongArch:Implement the new vector cost model framework.
