Ayal Zaks 08b77c4665 [LV] Report multiple reasons for not vectorizing under allowExtraAnalysis ... The default behavior of -Rpass-analysis=loop-vectorizer is to report only the first reason encountered for not vectorizing, if one is found, at which time the vectorizer aborts its handling of the loop. This patch allows multiple reasons for not vectorizing to be identified and reported, at the potential expense of additional compile-time, under allowExtraAnalysis which can currently be turned on by Clang's -fsave-optimization-record and opt's -pass-remarks-missed. Removed from LoopVectorizationLegality::canVectorize() the redundant checking and reporting if we CantComputeNumberOfIterations, as LAI::canAnalyzeLoop() also does that. This redundancy is caught by a lit test once multiple reasons are reported. Patch initially developed by Dror Barak.
