  Log Message:
  -----------
  [LV] Remove the EpilogueVectorizerMainLoop hierarchy level (NFC). (#227885)

EpilogueVectorizerMainLoop no longer overrides
createVectorizedLoopSkeleton; all it contributes are two debug traces.
Vectorize the main loop with a plain InnerLoopVectorizer and emit the
debug traces for both the main and the epilogue loop from processLoop,
removing the printDebugTraces* hooks.

That leaves InnerLoopAndEpilogueVectorizer with a single subclass and a
single member only used by the debug traces, so fold it into
EpilogueVectorizerEpilogueLoop and drop the member.
