  Log Message:
  -----------
  Extend BasicBlock sections to allow specifying clusters of basic blocks
in the same section.

This allows specifying BasicBlock clusters like the following example:
!foo
!!0 1 2
!!4
This places basic blocks 0, 1, and 2 in one section in this order, and
places basic block #4 in a single section of its own.
