787	add vtables for: get_pmc_keyed{_int,_str,}_lvalue ; and similarly for slice	japhb		"See discussion starting at:

In short, HLLs expect to be able to bind to an element (or slice) of a collection as an lvalue, even if that collection is implemented as a packed array of non-PMCs underneath the covers.  Indexing into a collection for rvalue return and for lvalue return are different operations; thus we need lvalue variants of get_pmc_keyed* to go along with the current rvalue variants, and the HLLs need to use the correct variant for the operation they wish to perform.
