embed.fnc: Add flag for bypass macro existence

Sometimes a function is reduced to be a wrapper, and we want for code to
directly call the underlying one, but we retain the old 'Perl_foo'
function to avoid breaking code that used that form.  I've tried various
kludges around that, but this seems more promising.
