svn merge -r36236:36306 http://codespeak.net/svn/pypy/branch/jit-codegen-refactor/pypy
Refactor a bit the codegen interface of the JIT, using
enter_next_block() less often. This should make register allocation
easier.
Fix an old obscure**42 problem that was always there, but not
found because show_incremental_progress() didn't call checkgraph().
Make reftracker robust against missing attributes.
Skip the real backend tests, to be able to merge the branch.
