This is the third (and penultimate) patch that https://reviews.llvm.org/D25580 is split into.
The test case will be added with the final patch.

In this patch, support for converting a vector of loads into a single load if the loads are consecutive (in either direction).
There is currently a limitation in that consecutive loads are not recognized if one of them is a pre-increment load.
