[issue2093] g++ failing on _mm_set1_epi32() (cc don't)

[Alex Hornung (via DragonFly issue tracker)]

>From what I can see this is due to an unaligned access with movdqa, which can
only be used with quad-word aligned addresses:

faulting instruction: 
movdqa -0x2c0(%rbp),%xmm0

registers:
rbp            0x7ffffffff3f8   0x7ffffffff3f8

Not sure why gcc is generating an unaligned access with MOVDQA.
