x86: Check each component of source operand for AVX_U128_DIRTY
commit 9775e465c1fbfc32656de77c618c61acf5bd905d
Author: H.J. Lu <hjl.tools@gmail.com>

x86: Don't set AVX_U128_DIRTY when zeroing YMM/ZMM register
called ix86_check_avx_upper_register to check mode on source operand.
But ix86_check_avx_upper_register doesn't work on source operand like
(vec_select:V2DI (reg/v:V4DI 23 xmm3 [orig:91 ymm ] [91])
(parallel [
(const_int 2 [0x2])
(const_int 3 [0x3])
]))
Add ix86_avx_u128_mode_source to check mode for each component of source
operand.

Call ix86_avx_u128_mode_source to check mode for each component
of source operand.
