  -----------
  [ObjC][ARC] Teach the OptimizeSequences step of ObjCARCOpts about WinEH funclet tokens

When optimizing retain-release-sequences we insert (and delete) ObjC runtime calls. These calls need a funclet operand bundle that refers to the enclosing funclet pad whenever they are inserted in a WinEH funclet. WinEH funclets can contain multiple basic blocks. In order to find the enclosing funclet pad, we have to calculate the funclet coloring first.

  Log Message:
  -----------
  [ObjC][ARC] Share bundle handling code between steps of the ObjCARCOpts pass and cleanup (NFC)

Generalize and share code for operand bundle handling. Drop the anonymous namespace (all other helper functions are local static). Rename the existing funclet test for cleanup-pads.
