...
If no alignment was set on the load/stores, it would vectorize
to the new type even though this increases the default alignment.

LoadStoreVectorizer: Fix assert when merging pointer ops
...

load. If a pointer is used always do an integer load.

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