2623a06878 LoadStoreVectorizer: Don't increase alignment with no align set 
If no alignment was set on the load/stores, it would vectorize
to the new type even though this increases the default alignment.

0b5646a61a LoadStoreVectorizer: Fix assert when merging pointer ops 
This needs to use inttoptr/ptrtoint if combining an int and pointer
load. If a pointer is used always do an integer load.

7e961b6fb8 LoadStoreVectorizer: Use AA metadata 
This was not passing the full instruction with metadata
to the alias query.

378e1693a1 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.

8b86030deb Add LoadStoreVectorizer pass 
This was contributed by Apple, and I've been working on
minimal cleanups and generalizing it.
