Irritatingly, the common fields contain quite big TLBs. And the
offsets from the start of env affect the compactness of the code
generated from TCG. We really really want the general registers
to come first to make sure that those offsets fit the host's
reg+offset addressing mode.
What about adding a 512-bytes (or more) block or something like that at
the beginning of CPUState with a union, so you can put the per-target
stuff there?
