Attached patch fixes all problems found with the mode of VEC_SELECT
RTXes in pmaddubsw patterns.

2011-03-03  Uros Bizjak  <ubizjak@gmail.com>

	* config/i386/sse.md (*avx_pmaddubsw128): Fix mode of VEC_SELECT RTX.
	(ssse3_pmaddubsw128): Ditto.
	(ssse3_pmaddubsw): Ditto.

Patch was bootstrapped and regression tested on x86_64-pc-linux-gnu
{,-m32} and will be committed to 4.6, 4.5 and 4.4 branches.

Thanks,
Uros.
