re PR target/59163 (program compiled with g++ -O3 segfaults)
PR target/59163
* config/i386/i386.c (ix86_legitimate_combined_insn): If for
!TARGET_AVX there is misaligned MEM operand with vector mode
and get_attr_ssememalign is 0, return false.
(ix86_expand_special_args_builtin): Add get_pointer_alignment
computed alignment and for non-temporal loads/stores also
at least GET_MODE_ALIGNMENT as MEM_ALIGN.
* config/i386/sse.md
