e920bab976 py/emitinline: Move common code for end of final pass to compiler. 
This patch moves some common code from the individual inline assemblers to
the compiler, the code that calls the emit-glue to assign the machine code
to the functions scope.

dd53b12193 py/emitinline: Move inline-asm align and data methods to compiler. 
These are generic methods that don't depend on the architecture and so
can be handled directly by the compiler.

a7fd786a1f py/emitinline: Embed entire asm struct instead of a pointer to it. 
This reduces fragmentation, and memory use by 1 word.  But more
importantly it means the emit_inline_asm_t struct now "derives" from
mp_asm_base.

612599587b py: Factor out common code from assemblers into asmbase.[ch]. 
All assemblers should "derive" from mp_asm_base_t.

28adab36c7 py/emitinlinethumb: Use qstrs instead of char* for names of asm ops. 
Reduces code size by 112 bytes on Thumb2 arch, and makes assembler faster
because comparison can be a simple equals instead of a string compare.

Not all ops have been converted, only those that were simple to convert
and reduced code size.

8f54c08691 py/inlineasm: Add ability to specify return type of asm_thumb funcs. 
Supported return types are: object, bool, int, uint.

For example:

@micropython.asm_thumb
def foo(r0, r1) -> uint:
    add(r0, r0, r1)

e813541e3f py: Add option for inline assembler to support ARMv7-M instructions. 
Cortex-M0, M0+ and M1 only have ARMv6-M Thumb/Thumb2 instructions.  M3,
M4 and M7 have a superset of these, named ARMv7-M.  This patch adds a
config option to enable support of the superset of instructions.

9988618e0e py: Implement full func arg passing for native emitter. 
This patch gets full function argument passing working with native
emitter.  Includes named args, keyword args, default args, var args
and var keyword args.  Fully Python compliant.

It reuses the bytecode mp_setup_code_state function to do all the hard
work.  This function is slightly adjusted to accommodate native calls,
and the native emitter is forced a bit to emit similar prelude and
code-info as bytecode.

04b9147e15 Add license header to (almost) all files.

difficult to deal with (license wise) so it was left out of those.
