[LispM-Hackers] BR-*-LIKELY

[James A. Crippen]

The BR-NULL-LIKELY and BR-NOT-NULL-LIKELY insns just came to my
attention.  These are described in defop-lisp-function-p.lisp:

;;; 174-177 are special BRANCH-LIKELY instructions
;;; Hummingbird hardware will follow these branches in the macro-pipeline

Anyone care to explain this obscurity?
