Changes since v2:
* Fix build for 32-bit host without 64-bit atomics.
Tested with --extra-cflags='-march=-i486'.
This is patch 15, which might ought to get folded back into
patch 13 for bisection, but is ugly for review.
* Move a lot of stuff out of softmmu_template.h, and into cputlb.c.
This is both for code size reduction and readability.
* Fold in Alex's test-int128 fix.
