r215162 fixes this bug.

[LLVMdev] MCJIT generates MOVAPS on unaligned address
It's not reproducible with 'opt'. I call the SLP pass from my
application and only then the wrong IR gets generated.
On the attached module I call via the function pass manager:
1) TargetLibraryInfo with the target triple
2) Set the data layout
3) Basic Alias Analysis
4) SLP vectorizer
This produces the wrong IR. On the other hand running the attached
module through 'opt
