Improve for-effect handling in a few places, lisp/
lisp/ChangeLog addition:
2012-05-01 Aidan Kehoe <kehoea@parhasard.net>
* byte-optimize.el (byte-optimize-form-code-walker):
* byte-optimize.el (byte-optimize-or):
Improve handling of for-effect here; we don't need to worry about
discarding multiple values when for-effect is non-nil, this
applies to both #'prog1 and #'or.
* bytecomp.el (progn):
* bytecomp.el (byte-compile-file-form-progn): New.
Put back this function, since it's for-effect there's no need to
worry about passing back multiple values.
* cl-macs.el (cl-pop2):
* cl-macs.el (cl-do-pop):
* cl-macs.el (remf):
* cl.el (pop):
Expand to (prog1 (car-safe PLACE) (setq PLACE (cdr PLACE))) in all
these macros, since that optimizes better (especially for-effect
handling) when byte-compile-delete-errors is nil.
