The scanner for spotting closure creation bytecodes in methods must identify full block closure creations.

=============== Diff against Compiler-eem.384 ===============

Item was changed:
  ----- Method: EncoderForSistaV1 class>>createClosureScanBlock (in category 'compiled method support') -----
  createClosureScanBlock
  "Answer a block argument for InstructionStream>>scanFor: that answers true
+ for block closure creation bytecodes.  Note that with this interface we can't answer
- for block closure creation bytecodes.  ote that with this interface we can't answer
  true for the extension in front of a push closure bytecode and so the interface may
  have to change at some point."
