d91aab4dd6814ca54c211a93fec3f072745a52c4 Docs: Address -fivopts, -O0, and -Q confusion [PR71094]
There's a blurb at the top of the "Optimize Options" node telling
people that most optimization options are completely disabled at -O0
and a similar blurb in the entry for -Og, but nothing at the entry for
-O0. Since this is a continuing point of confusion it seems wise to
duplicate the information in all the places users are likely to look
for it.

* doc/invoke.texi (Optimize Options): Document that -fivopts is
enabled at -O1 and higher. Add blurb about -O0 causing GCC to
completely ignore most optimization options.
