try yet another way to encode bytecodes; this time, opargs are decoded
in advance, but they are stored togheter with the opcodes in a list of
ints. This code is not very well tested nor well written, I commit it
just to do benchmarks on different machines - 20077. By antocuni

experimental option that precomputes opcode args and pack the bytecode
to contains only opcodes, not opargs; the intent is to make the
interpreter loop a bit smaller.The benchmarks are a bit controversial, it's not clear if you win or
loose. - 20074. By cami

renamed constants of timer and serlial for better readability
adaoted tests
fixed bug in interrupt: enable is not a bool its an int!
adapted tests
minor refactoring: mostly code formattinh - 20072. By arigo

Experimental check-in which could be reverted. This makes the method
cache global instead of per-thread.It makes a pypy-c-thread almost as fast as a pypy-c-no-thread, when
threads are not used (<2% difference). The reason is that
getexecutioncontext() needs to call RPyThreadIdent(), which appears to
be the main cause of a global slow-down of 4-5%. I don't know if there
are real-world cases where the method cache would get significantly
trashed by being shared between threads.An alternative to this check-in would be to improve
getexecutioncontext(), e.g. by replacing the dict {thread_id:
executioncontext} with a single executioncontext reference which is
carefully saved and restored when the GIL is released. For now it would
be too much cleverness for too little gain, so I'll skip.
