74eb44c392 py: Reduce size of VM exception stack element by 1 machine word. 
This optimisation reduces the VM exception stack element (mp_exc_stack_t)
by 1 word, by using bit 1 of a pointer to store whether the opcode was a
FINALLY or WITH opcode.  This optimisation was pending, waiting for
maturity of the exception handling code, which has now proven itself.

Saves 1 machine word RAM for each exception (4->3 words per exception).
Increases stmhal code by 4 bytes, and decreases unix x64 code by 32
bytes.

584ba6762f py: Move global/nonlocal decl code to compiler for proper SyntaxError. 
This patch gives proper SyntaxError exceptions for bad global/nonlocal
declarations.  It also reduces code size: 304 bytes on unix x64, 132
bytes on stmhal.

978f4ca2e1 run-tests: Allow to run testuite against Windows build on Linux (using Wine). 
Just adjust line-endings of micropython.exe output, the rest should be
handled by Wine (automagically on properly configured distro).

To run:

MICROPY_MICROPYTHON=../windows/micropython.exe ./run-tests

f04329e93b lib/libm: Add acosh, asinh, atanh, tan; get working with stmhal. 
acoshf, asinhf, atanhf were added from musl.  mathsincos.c was
split up into its original, separate files (from newlibe-nano-2).
tan was added.

All of the important missing float functions are now implemented,
and pyboard now passes tests/float/math_fun.py (finally!).

e181c0dc07 py: Fix optimised for-loop compiler so it follows proper semantics. 
You can now assign to the range end variable and the for-loop still
works correctly.  This fully addresses issue #565.

Also fixed a bug with the stack not being fully popped when breaking out
of an optimised for-loop (and it's actually impossible to write a test
for this case!).

78d702c300 py: Allow builtins to be overridden. 
This patch adds a configuration option (MICROPY_CAN_OVERRIDE_BUILTINS)
which, when enabled, allows to override all names within the builtins
module.  A builtins override dict is created the first time the user
assigns to a name in the builtins model, and then that dict is searched
first on subsequent lookups.  Note that this implementation doesn't
allow deleting of names.

This patch also does some refactoring of builtins code, creating the
modbuiltins.c file.

Addresses issue #959.
