Move #'split-path to subr.el, as was always the intention.
lisp/ChangeLog addition:
2011-05-07 Aidan Kehoe <kehoea(a)parhasard.net>
* subr.el:
* subr.el (split-path): New.
Moved here from fns.c. There's no need to have this in C, it's no
longer used that early at startup.

environment is not a symbol, as is the case for symbol macros.
* bytecomp.el (or):
Use slightly better style when compiling the most important
functions if bytecomp.el has just been loaded interpreted.

Drop support for generating code appropriate for Emacs 19, bytecomp.el
lisp/ChangeLog addition:
2011-05-07 Aidan Kehoe <kehoea(a)parhasard.net>
* bytecomp.el:
* bytecomp.el (byte-compile-two-args-19->20): Removed.
* bytecomp.el (byte-compile-emacs19-compatibility): Removed.
* bytecomp.el (byte-defop-compiler20): Removed.
* bytecomp.el (byte-defop-compiler-rmsfun): Removed.
* bytecomp.el (emacs-lisp-file-regexp):
* bytecomp.el (byte-compile-print-gensym):
* bytecomp.el (byte-compiler-legal-options):
* bytecomp.el (byte-compiler-obsolete-options):
* bytecomp.el (byte-compile-close-variables):

* bytecomp.el (byte-compile-out-toplevel):
* bytecomp.el (byte-compile-form):
* bytecomp.el (byte-defop-compiler-1):
* bytecomp.el (eq):
* bytecomp.el (equal):
* bytecomp.el (member):
* bytecomp.el (byte-compile-noop):
* bytecomp.el (byte-compile-save-current-buffer):
Remove support for generating code appropriate to Emacs 19.
* bytecomp.el (byte-compile-eval):
Avoid erroring here if the car of some entry in the macro
environment is not a symbol, as is the case for symbol macros.
* bytecomp.el (or):
Use slightly better style when compiling the most important
functions if bytecomp.el has just been loaded interpreted.

* byte-optimize.el:
* byte-optimize.el (byte-optimize-form-code-walker):
Call #'byte-optimize-side-effect-free-p on the form, rather than
just checking the plist of the form's car.
* byte-optimize.el (side-effect-free-fns):
Move the CL functions into their alphabetical place in the list.
* byte-optimize.el (function):
* byte-optimize.el (byte-optimize-side-effect-free-p): New.
Function returning non-nil if a funcall has no side-effects, which
handles things like (remove* item list :key 'car) and
(remove-if-not #'integerp list).

Be better about recognising side-effect-free forms, byte-optimize.el.
2011-05-07 Aidan Kehoe <kehoea(a)parhasard.net>
* byte-optimize.el:
* byte-optimize.el (byte-optimize-form-code-walker):
Call #'byte-optimize-side-effect-free-p on the form, rather than
just checking the plist of the form's car.
* byte-optimize.el (side-effect-free-fns):
Move the CL functions into their alphabetical place in the list.
* byte-optimize.el (function):
* byte-optimize.el (byte-optimize-side-effect-free-p): New.
Function returning non-nil if a funcall has no side-effects, which
handles things like (remove* item list :key 'car) and
(remove-if-not #'integerp list).
