Fork of llvm with experimental commits and workarounds for RPCS3

(This is the second attempt to check in this patch: REQUIRES: asserts is added to reg-usage.ll now.) LoopVectorizationCostModel::calculateRegisterUsage() is used to estimate the register usage for specific VFs. However, it takes into account many instructions that won't be vectorized, such as induction variables, GetElementPtr instruction, etc.. This makes the loop vectorizer too conservative when choosing VF. In this patch, the induction variables that won't be vectorized plus GetElementPtr instruction will be added to ValuesToIgnore set so that their register usage won't be considered any more.
