Changed, also adjust ix86_check_avx_upper_stores and ix86_avx_u128_mode_needed
to either inline the old ix86_check_avx_upper_register or replace

For function arguments/return, when it's BLK mode, it's put in a
parallel with an expr_list, and the expr_list contains the real mode
and registers.
Current ix86_check_avx_upper_register only checked for SSE_REG_P, and
failed to handle that. The patch extend the handle to each subrtx.
Bootstrapped
