For Hexagon, peeling loops with small runtime trip count is beneficial for our
benchmarks. We set PeelCount in HexagonTargetInfo.cpp and we use PeelCount set
by the target for computing the desired peel count.

This implements a set of TTI functions that the loop vectorizer uses.
The only purpose of this is to enable testing. Auto-vectorization is
disabled by default, enabled by -hexagon-autohvx.

The changes are a result of discussion of https://reviews.llvm.org/D33685.
It solves the following problem:
1. We can inform getGEPCost about simplified indices to help it with
calculating the cost. But getGEPCost does not take into account the
context which GEPs are used in.
2. We have getUserCost which can take the context into account but we cannot
inform about simplified indices.
With the changes getUserCost will have access to additional information
as getGEPCost has.
The one parameter getUserCost is also provided.
