  [ICP] Add a few tunings to indirect-call-promtion

Indirect-call promotion (ICP) has been adjusted with the following
tunings.
  (1) Candidate functions can be now ICP'd even if only a declaration
      is present.
  (2) All non-cold candidate functions are now considered by ICP.
      Previously, only hot targets were considered.
In this patch, both tunings are disabled by default. They will be
enabled in a subsequent patch.
