[pypy-dev] jit-short_from_state

[Hakan Ardo]

Hi,
what I had in mind for jit-short_from_state is now in place and seem
to be working. So if anyone feels like reviewing now is a good time :)
Benchmarks show ai 15% faster, spectral-norm 47% faster and bm_mako
11% slower as compared to trunk. The others are not affected much:

There are still 3 test_pypy_c tests failing due worse optimization:

Addressing those would need some though though...
