  Log Message:
  [BOLT] Process fragment siblings in lite mode, keep lite mode on

In lite mode, include split function fragments to the list of functions to
process even if a fragment has no samples. This is required to properly
detect and update split jump tables (jump tables that contain pointers to code
in the main and cold fragments).
