Matt Arsenault 241f34cde8 LoadStoreVectorizer: Use AA metadata 
This was not passing the full instruction with metadata
to the alias query.

Matt Arsenault d7e8898bdd LoadStoreVectorizer: if one element of a vector is integer, default to 
integer.

Fixes issues on some architectures where we use arithmetic ops to build
vectors, which can cause bad things to happen for loads/stores of mixed
types.
