[JSC] holesMustForwardToPrototype should be fast for normal arrays
https://bugs.webkit.org/show_bug.cgi?id=259239
rdar://112308103
Reviewed by Alexey Shvayka.
We should quickly say `false` from Structure::holesMustForwardToPrototype if
the target structure
is original array and we are having array prototype sane chain (this means we
have no indexed properties,
and array prototype chain is solid).
