tests/bytecode/run-tests already uses puthon3.3, so let's just use it here
too.
Fore reference, errors with python 3.2.3:
File "tests/generator1.py", line 12
return None
SyntaxError: 'return' with argument inside generator
File "tests/list_clear.py", line 3, in <module>
x.clear()
AttributeError: 'list' object has no attribute 'clear'
etc.
Qstr's are now split into a linked-list of qstr pools. This has 2
benefits: the first pool can be in ROM (huge benefit, since we no longer
use RAM for the core qstrs), and subsequent pools use m_new for the next
pool instead of m_renew (thus avoiding a huge single table for all the
qstrs).
Still would be better to use a hash table, but this scheme takes us part
of the way (eventually convert the pools to hash tables).
Also fixed bug with import.
Also improved the way the module code is referenced (not magic number 1
anymore).
With MICROPY_EMIT_X64 and MICROPY_EMIT_THUMB disabled, the respective
emitters and assemblers will not be included in the code. This can
significantly reduce binary size for unix version.
