Andreas Kling b4185f0ecd LibJS: Split packed and holey asm indexed fast paths ...

Use dedicated Packed branches in GetByValue and PutByValue so
in-bounds indexed accesses can skip hole checks and slot
reloads.

Keep Holey writes on the guarded arm, and keep append writes on
the C++ slow path so PutByValue still respects non-extensible
indexed objects and arrays with a non-writable length.

Add a bytecode regression that exercises both append failure
cases through the real js binary path.
