Remove VarExists

This patch (including Fortran and Java pieces, though I consider those
obvious), relative to a tree with
<http://gcc.gnu.org/ml/gcc-patches/2010-09/msg02171.html> (pending
review of the non-front-end pieces) applied, removes the VarExists
markers from .opt files and the documentation for VarExists.  As
discussed in that previous message, nothing makes use of VarExists
information after that patch.

Bootstrapped with no regressions on x86_64-unknown-linux-gnu.  OK to
commit?

2010-09-29  Joseph Myers  <joseph@codesourcery.com>

	* doc/options.texi (Variable, Var, Init): Update documentation
	without reference to VarExists.
	(VarExists): Remove.
	* common.opt, config/i386/i386.opt, config/linux.opt,
	config/rs6000/rs6000.opt, config/sh/sh.opt, config/spu/spu.opt:
	Don't use VarExists.
