add PL_sv_zero
it's like PL_sv_no, except that its string value is "0" rather than "".
It can be used for example where pp function wants to push a zero return
value on the stack. The next commit will start to use it.
Also update the SvIMMORTAL() to be more efficient: it now checks whether
the SV's address is in a range rather than individually checking against
&PL_sv_undef, &PL_sv_no etc.
