Just pushed it to the scratch/igc branch. It shouldn't have any effect
on ordinary 64-bit builds; some of the code is to cater to the
hypothetical big-endian 32-bit use case, and technically the x86 MPS
weak pointer "optimization" could bite us again, but recent GCC does not
generate the precise instructions that MPS emulates, so I'll risk it.

As I've just explained, bug reports for the WIDE_EMACS_INT case will be
difficult to deal with, as there are two major changes; let's see what
happens, but I suspect we'll end up having to ask users to build a !MPS
+ USE_LSB_TAG + WIDE_EMACS_INT configuration.
