OP_AELEMFASTLEX_STORE - combined sassign/aelemfast_lex

This commit introduces a new OP to replace simple cases of OP_SASSIGN
and OP_AELEMFAST_LEX. (Similar concept to GH #19943)

For example, `my @ary; $ary[0] = "boo"` is currently implemented as:
    7     <2> sassign vKS/2 ->8
    5        <$> const[PV "boo"] s ->6
    -        <1> ex-aelem sKRM*/2 ->7
    6           <0> aelemfast_lex[@ary:1,2] sRM ->7
    -           <0> ex-const s ->-

But now will be turned into:
    6     <1> aelemfastlex_store[@ary:1,2] vKS ->7
    5        <$> const(PV "boo") s ->6
    -        <1> ex-aelem sKRM*/2 ->6
    -           <0> ex-aelemfast_lex sRM ->6
    -           <0> ex-const s ->-

This is intended to be a transparent performance optimization.
It should be applicable for RHS optrees of varying complexity.
