With or without PGO data applied, splitting early in the pipeline (either before the inliner or shortly after it) regresses performance across SPEC variants. The cause appears to be that splitting hides context for subsequent optimizations. Schedule splitting late again, in effect reversing r352080, which scheduled the splitting pass early for code size benefits (documented in https://reviews.llvm.org/D57082).
