[PATCH] Document -fipa-vrp

Hi,

I have noticed that -fipa-vrp was not documented in
gcc/doc/invoke.texi so I propose the following.  When at ti, I took
the liberty of replacing "ipa" with "interprocedural" in the
description of -fipa-bit-cp.

Tested with make info, OK for trunk?

Thanks,

Martin

	* doc/invoke.texi (Option Options): Include -fipa-vrp in the list.
	(List of -O2 options): Likewise.
	(-fipa-bit-cp): Replace "ipa" with "interprocedural."
	(-fipa-vrp) New.
