[PATCH]: grammar and spelling fixes in invoke.texi

[Jerry Quinn <jlquinn at optonline dot net>]

This is some minor spelling and grammar fixes, originally just in the
optimize flags section, but then I spell-checked the whole file and
found a few more nits.  The original patch was conditionally approved here:

http://gcc.gnu.org/ml/gcc-patches/2002-09/msg00952.html

I have a copyright assignment in place now and the fixes asked for by
Geoff are included.
