[PGO] Make pgo related options in opt more consistent. Currently we have pgo options defined in PassManagerBuilder.cpp only for instrument pgo, but not for sample pgo. We also have pgo options defined in NewPMDriver.cpp in opt only for new pass manager and for all kinds of pgo. They have some inconsistency. To make the options more consistent and make tests writing easier, the patch let old pass manager to share the same pgo options with new pass manager in opt, and removes the options in PassManagerBuilder.cpp. Differential Revision: https://reviews.llvm.org/D56749 llvm-svn: 351392

I've also added --dump-input=fail to the new tests so I can more thoroughly fix any additional failures.

[HotColdSplit] Move splitting after instrumented PGO use Summary: Follow up to D57082 which moved splitting earlier in the pipeline, in order to perform it before inlining. However, it was moved too early, before the IR is annotated with instrumented PGO data. This caused the splitting to incorrectly determine cold functions. Move it to just after PGO annotation (still before inlining), in both pass managers.

[HotColdSplit] Schedule splitting late to fix perf regression 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).
