Address two correctness issues in LoadStoreVectorizer
...
Summary:
GetBoundryInstruction returns the last instruction as the instruction which follows or end(). Otherwise the last instruction in the boundry set is not being tested by isVectorizable().
Partially solve reordering of instructions. More extensive solution to follow.

LoadStoreVectorizer: improvements: better pointer analysis
...
If OpB has an ADD NSW/NUW, we can use that to prove that adding 1
to OpA won't wrap if OpA + 1 == OpB.

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.

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.

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.

minimal cleanups and generalizing it.
