Yes.

(To see what kinds of output this "dump all options" might give, compile
something with "-S -fverbose-asm" and then look at the comments at the
top of the assembly output file.)

For this to be more useful, we'd have to annotate the printed options with
some "this has been changed from the spec'd default" marker, e.g.,

    -ffoo -fbar *-fuser-added -fbaz


There's also a standing wishlist request for storing the options into the
.o file.  I stopped working on that one for similar reasons.
