Get rid of PL_formfeed.

$^L is neither a magical variable, nor a normal one (like $;) but
it's just a little bit special :)

This patch removes PL_formfeed - IMHO, an extra gv_fetchpv per page
when using formats isn't going to cause a sensible speed regression.

I suppose that removing the intrpvar.h hunk from the patch is enough
to keep binary compatibility - unless someone used PL_formfeed from
an XS module.

[with regen.pl run as noted by the author, and an additional change to
perl.c to remove the reference to PL_formfeed added soon after this patch
was sent]
