Document already has been reviewed. This patch adds OPTAB/IFN support as follows: 1. strided load GIMPLE level: v = MASK_LEN_STRIDED_LOAD (ptr, stride, mask, len, bias) be expand (by internal-fn.cc) into: v = mask_len_strided_load (ptr, stried, mask, len, bias) 2. strided store GIMPLE leve: MASK_LEN_STRIED_STORE (ptr, stride, v, mask, len, bias) be expand (by internal-fn.cc) into: mask_len_stried_store (ptr, stride, v, mask, len, bias) Bootstrap and regression on X86 no regression.
