882b363564 py: Move to Python 3.4.0 compatibility. 
Very little has changed.  In Python 3.4 they removed the opcode
STORE_LOCALS, but in Micro Python we only ever used this for CPython
compatibility, so it was a trivial thing to remove.  It also allowed to
clean up some dead code (eg the 0xdeadbeef in class construction), and
now class builders use 1 less stack word.

Python 3.4.0 introduced the LOAD_CLASSDEREF opcode, which I have not
yet understood.  Still, all tests (apart from bytecode test) still pass.
Bytecode tests needs some more attention, but they are not that
important anymore.

3ff2d03891 py: Fix bug in optimised for .. range. 
Don't store final, failing value to the loop variable.  This fix also
makes for .. range a bit more efficient, as it uses less store/load
pairs for the loop variable.

96eec4f8a6 compile: Don't try to constant-fold division by zero. 
The way it is, just crashes app. And optimizing to
"raise ZeroDivisionError" is probably too much.

d17926db71 Rename rt_* to mp_*. 
Mostly just a global search and replace.  Except rt_is_true which
becomes mp_obj_is_true.

Still would like to tidy up some of the names, but this will do for now.

d1e443d0bc py: Free unique_code slot for outer module. 
Partly (very partly!) addresses issue #386.  Most importantly, at the
REPL command line, each invocation does not now lead to increased memory
usage (unless you define a function/lambda).

bbf0e2fe12 parse: Note that fact that parser's small ints are different than VM small int. 
Specifically, VM's small ints are 31 bit, while parser's only 28. There's already
MP_OBJ_FITS_SMALL_INT(), so, for clarity, rename MP_FIT_SMALL_INT() to
MP_PARSE_FITS_SMALL_INT().

90750029df Implement default function arguments (for Python functions). 
TODO: Decide if we really need separate bytecode for creating functions
with default arguments - we would need same for closures, then there're
keywords arguments too. Having all combinations is a small exponential
explosion, likely we need just 2 cases - simplest (no defaults, no kw),
and full - defaults & kw.

08d075592f py: Fix bug with LOAD_METHOD; fix int->machine_int_t for small int. 
LOAD_METHOD bug was: emitbc did not correctly calculate the amount of
stack usage for a LOAD_METHOD operation.

small int bug was: int was being used to pass small ints, when it should
have been machine_int_t.

899c69f94c compile_for_stmt_optimised_range(): Properly handle negative & unknown steps. 
If step is not constant, in first approximation, we can't apply optimization,
(well, we could, but need a special case for this).
