Andreas Kling 4c1e2222df LibJS: Fast-path safe writes into holey array holes 
Teach the asm PutByValue path to materialize in-bounds holey array
elements directly when the receiver is a normal extensible Array with
the default prototype chain and no indexed interference. This avoids
bouncing through generic property setting while preserving the lazy
holey length model.

Keep the fast path narrow so inherited setters, inherited non-writable
properties, and non-extensible arrays still fall back to the generic
semantics. Add regression coverage for those cases alongside the large
holey array stress tests.
