fcc9cf63f1 py, str: Replace enum with actual function pointer. 
This way, it's slightly more efficient, uses less ROM (60 bytes less
for stmhal), and doesn't require to raise exception if bad operation
given.

fb510b3bf9 Rename bultins config variables to MICROPY_PY_BUILTINS_*. 
This renames:
MICROPY_PY_FROZENSET -> MICROPY_PY_BUILTINS_FROZENSET
MICROPY_PY_PROPERTY -> MICROPY_PY_BUILTINS_PROPERTY
MICROPY_PY_SLICE -> MICROPY_PY_BUILTINS_SLICE
MICROPY_ENABLE_FLOAT -> MICROPY_PY_BUILTINS_FLOAT

See issue #35 for discussion.

c60a261ef0 py, vm: Replace save_ip, save_sp with code_state->{ip, sp}. 
This may seem a bit of a risky change, in that it may introduce crazy
bugs with respect to volatile variables in the VM loop.  But, I think it
should be fine: code_state points to some external memory, so the
compiler should always read/write to that memory when accessing the
ip/sp variables (ie not put them in registers).

Anyway, it passes all tests and improves on all efficiency fronts: about
2-4% faster (64-bit unix), 16 bytes less stack space per call (64-bit
unix) and slightly less executable size (unix and stmhal).

The reason it's more efficient is save_ip and save_sp were volatile
variables, so were anyway stored on the stack (in memory, not regs).
Thus converting them to code_state->{ip, sp} doesn't cost an extra
memory dereference (except maybe to get code_state, but that can be put
in a register and then made more efficient for other uses of it).

1b87d1098a Merge branch 'vm-alloca' of github.com:pfalcon/micropython into pfalcon-vm-alloca 
Conflicts:
	py/vm.c

Fixed stack underflow check.  Use UINT_FMT/INT_FMT where necessary.
Specify maximum VM-stack byte size by multiple of machine word size, so
that on 64 bit machines it has same functionality as 32 bit.

b4ebad3310 vm: Factor out structure with code execution state and pass it around. 
This improves stack usage in callers to mp_execute_bytecode2, and is step
forward towards unifying execution interface for function and generators
(which is important because generators don't even support full forms
of arguments passing (keywords, etc.)).

b16523aa95 vm: Don't unconditionally allocate state on stack, do that only if needed. 
This makes sure that only as much stack allocated as actually used, reducing
stack usage for each Python function call.

d8675541a9 py, vm: Where possible, make variables local to each opcode. 
This helps the compiler do its optimisation, makes it clear which
variables are local per opcode and which global, and makes it consistent
when extra variables are needed in an opcode (in addition to old obj1,
obj2 pair, for example).

Could also make unum local, but that's for another time.

f600a6a085 py: Slightly improve efficiency of mp_obj_new_str; rename str_new. 
Reorder interning logic in mp_obj_new_str, to be more efficient.

str_new is globally accessible, so should be prefixed with mp_obj_.

2617eebf2f Change const byte* to const char* where sensible. 
This removes need for some casts (at least, more than it adds need
for new casts!).

5042bce8fb py: Don't automatically intern strings in parser. 
This completes non-automatic interning of strings in the parser, so that
doc strings don't take up RAM.  It complicates the parser and compiler,
and bloats stmhal by about 300 bytes.  It's complicated because now
there are 2 kinds of parse-nodes that can be strings: interned leaves
and non-interned structs.
