  -----------
  [CSSPGO] Trim cold base profiles for the CS preinliner.

Adding support to the CS preinliner to trim cold base profiles. This makes trimming consistent with the inline decision made by the preinliner. Also disable the existing profile merger when preinliner is on unless explicitly specified.
