[Bug lto/41554] New: -flto and -fwhopr should be moved to common.opt

[dnovillo at gcc dot gnu dot org]

Both options are now recognized by individual front ends.  They should be moved
to common.opt.  Individual front end validation could be done via a langhook.

> Not set for gnat1 (Ada):

LTO doesn't work for Ada because of the sizetype issue.  I have a patch to make
it sort of work for pure Ada code, but mixed-language support is out of
question for the time being, we'll need to switch Ada to unsigned sizetype
first.

Likewise, -Wabi and -Wpsabi belong on common.opt, and the post_options
processing belongs in common code not in individual front ends.

Hmm, -flto and -fwhopr are in common.opt.  The -Wpsabi and -Wabi options are
not, but I fail to see why this is the fault of LTO.

I have a patch to move the -flto / -fwhopr postprocessing to common code.

Fixed.  -Wabi and -Wpsabi is a non-LTO specific issue.
