Patch for Valgrind support in compile.el

[Ole Aamot <ole@gnu.org>]

The patch is against emacs/lisp/progmodes/compile.el on
subversions.gnu.org.  (I assign the change to the FSF.)

Happy hacking.

	* compile.el: Add regexp for Valgrind (a memory debugger
	for x86-GNU/Linux) inside compilation-error-regexp-alist.

	Kudos to Hans Petter Jansson <hpj@ximian.com> for regexp.
