This refactors boolean 'OptForSize' that was passed around in a lot of places. It controlled folding of the tail loop, the scalar epilogue, into the main loop but code-size reasons may not be the only reason to do this. Thus, this is a first step to generalise the concept of tail-loop folding, and hence OptForSize has been renamed and is using an enum ScalarEpilogueStatus that holds the status how the epilogue should be lowered. This will be followed up by D65197, that picks up the predicate loop hint and performs the tail-loop folding. Differential Revision: https://reviews.llvm.org/D64916 llvm-svn: 366993
