Damien George 1e1779eacf py: Reluctantly add an extra pass to bytecode compiler.
Bytecode also needs a pass to compute the stack size.  This is because
the state size of the bytecode function is encoded as a variable uint,
so we must know the value of this uint before we encode it (otherwise
the size of the generated code changes from one pass to the next).

Having an entire pass for this seems wasteful (in time).  Alternative is
to allocate fixed space for the state size (would need 3-4 bytes to be
general, when 1 byte is usually sufficient) which uses a bit of extra
RAM per bytecode function, and makes the code less elegant in places
where this uint is encoded/decoded.

So, for now, opt for an extra pass.

This directory contains tests for various functionality areas of MicroPython.
To run all stable tests, run "run-tests" script in this directory. Note
that bytecode tests are not yet stable and should be run separately in
"bytecode" subdirectory.

When creating new tests, anything that relies on float support should go in the 
float/ subdirectory.  Anything that relies on import x, where x is not a built-in
module, should go in the import/ subdirectory.
