Implement OP_PADSV_STORE - combined sassign/padsv OP
This commit introduces a new OP to replace simple cases
of OP_SASSIGN and OP_PADSV.
For example, 'my $x = 1' is currently implemented as:
1 <;> nextstate(main 1 -e:1) v:{
2 <$> const(IV 1) s
3 <0> padsv[$x:1,2] sRM*/LVINTRO
4 <2> sassign vKS/2
But now will be turned into:
1 <;> nextstate(main 1 -e:1) v:{
2 <$> const(IV 1) s
3 <1> padsv_store[$x:1,2] vKMS/LVINTRO
This intended to be a transparent performance optimization.
It should be applicable for RHS optrees of varying complexity.
