  -----------
  [Pass][CHR] Move ControlHeightReduction to module optimization pipeline

This is a modified version of commit b374423304a8 by
Arthur (https://reviews.llvm.org/D143424).

Here we invoke to the pass independent of PGOOPT. We now check if the
profile is available through the program summary. This ensures CHR is
called in distributed ThinLTO BE compilation (where PGOOPT might not
be created).
