Hello!
This patch avoids movdqu/movdqa when SSE2 is disabled. Although
-mno-sse2 is bordering on ABI violation for 64bit targets, the patch
is simple enough to fix movti_internal_rex64 pattern.

* config/i386/i386.md (*movti_internal_rex64): Emit movaps/movups
for non-sse2 targets.
Tested on x86_64-pc-linux-gnu {,-m32}. OK for 4.8 branch?
(The patch is also needed for 4.7 branch, but not for mainline, where
this problem is fixed by movti_internal/movti_internal_rex64 merge).
Uros.
