Properly handle AVX256 unaligned load and store
PR target/59084 * config/i386/i386.c (ix86_option_override_internal): Check X86_TUNE_AVX256_UNALIGNED_LOAD_OPTIMAL and X86_TUNE_AVX256_UNALIGNED_STORE_OPTIMAL for MASK_AVX256_SPLIT_UNALIGNED_LOAD and MASK_AVX256_SPLIT_UNALIGNED_STORE. * config/i386/x86-tune.def (X86_TUNE_AVX256_UNALIGNED_LOAD_OPTIMAL): Clear m_COREI7_AVX and update comments. (X86_TUNE_AVX256_UNALIGNED_STORE_OPTIMAL): Likewise. From-SVN: r204700
