This isn't a systemic problem; I think it's just a handful of places that incorrectly assume that the offset of the low bits is zero. These have crept in because JSC is mainly just tested on little endian hardware.

As I have access to big endian hardware and I definitely could devote time to fix these issues. But I will need some help in beginnings, and I will contact you off the bugzilla..
