Please see the new revision. It passes `java/util/stream` tests on both `x86_32` and `x86_64`. What 32-bit VM is able to do is implementation-dependent, no? I do wonder if long[]/double[] have to be aligned by 8 anyway, since we can do a VarHandle atomic access over its elements, and it is supposed to go correctly. Let's figure that out separately?
