I changed the code to directly construct a slow array, but that lost the length property, which is only created as a dense array is slowified. Insane.

This patch removes a change I did before (make array.proto be constructed as slow arrays right away).

patch
The js_InitClass reversion is good, hope we can avoid any special-casing there if we try again to have js_InitArrayClass init js_SlowArrayClass not js_ArrayClass.

I don't think that does what you think it does: you really want
Object.getOwnPropertyNames(Array.prototype).indexOf("length") >= 0
Right?

Mhm. Right. That test is a little stupid. Want to fix it? On an iphone.
