Cache the signal number or -1 in mg_private, to reduce calls to Perl_whichsig().
It doesn't matter that 0 isn't cacheable, as the logic in Perl_magic_setsig()
is such that we already can't "set" $SIG{ZERO}. Without this we make thousands
of failing calls to Perl_whichsig() from Perl_magic_getsig() for "__WARN__".
