[Bug c/30719] gcc should probably warn if users compile without -O

[pinskia at gcc dot gnu dot org]

To me a warning should not be emitted while using -Wall -O0 as it will break
all the programs which use -Werror which is a lot of them.  Also this is
already documented, if people don't read documentation, why would they read
warnings?
