[PATCH, i386]: Fix handling of TARGET_SSE_TYPELESS_STORES in unaligned move RTXes

[Uros Bizjak]

Hello!

When unaligned moves were split to unaligned store/loads, mode
calculation didn't get updated. Attached patch fixes this oversight.

2012-11-25  Uros Bizjak  <ubiz...@gmail.com>

        * config/i386/sse.md (<sse>_loadu<ssemodesuffix><avxsizesuffix>):
        Do not depend on TARGET_SSE_TYPELESS_STORES.
        (<sse2>_loaddqu<avxsizesuffix>): Ditto.
        (<sse>_storeu<ssemodesuffix><avxsizesuffix>): Fix handling of
        TARGET_SSE_TYPELESS_STORES.
        (<sse2>_storedqu<avxsizesuffix>): Ditto.

Tested on x86_64-pc-linux-gnu {,-m32} and committed to mainline SVN.

Uros.
