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. r~ Emilio G.
