This commit adds support for saving and loading .mpy files that contain native code (native, viper and inline-asm). A lot of the ground work was already done for this in the form of removing pointers from generated native code. The changes here are mainly to link in qstr values to the native code, and change the format of .mpy files to contain native code blocks (possibly mixed with bytecode). A top-level summary: - @micropython.native, @micropython.viper and @micropython.asm_thumb/ asm_xtensa are now allowed in .py files when compiling to .mpy, and they work transparently to the user. - Entire .py files can be compiled to native via mpy-cross -X emit=native and for the most part the generated .mpy files should work the same as their bytecode version. - The .mpy file format is changed to 1) specify in the header if the file contains native code and if so the architecture (eg x86, ARMV7M, Xtensa); 2) for each function block the kind of code is specified (bytecode, native, viper, asm). - When native code is loaded from a .mpy file the native code must be modified (in place) to link qstr values in, just like bytecode (see py/persistentcode.c:arch_link_qstr() function). In addition, this now defines a public, native ABI for dynamically loadable native code generated by other languages, like C.
