Perl_newSV_type_mortal - new inline function introduced and used
There's no efficient way to create a mortal SV of any type other than
SVt_NULL (via sv_newmortal). The options are either to do:
* SV* sv = sv_newmortal; sv_upgrade(sv, SVt_SOMETYPE);
but sv_upgrade is needlessly inefficient on new SVs.
* SV* sv = sv_2mortal(newSV_type(SVt_SOMETYPE)
but this will perform runtime checks to see if (sv) and if (SvIMMORTAL(sv),
and for a new SV we know that those answers will always be yes and no.
This commit adds a new inline function which is basically a mortalizing
wrapper around the now-inlined newSV_type.
