35f3f0a87d py/nlr: Add "memory" to asm clobbers list in nlr_jump. 
Newer versions of gcc (14 and up) have more sophisticated dead-code
detection, and the asm clobbers list needs to contain "memory" to inform
the compiler that the asm code actually does something.

Tested that adding this "memory" line does not change the generated code on
ARM Thumb2, x86-64 and Xtensa targets (using gcc 13.2).

Fixes issue #14115.

40a3aa709c py/nlrmips: Add native NLR support for MIPS architecture. 
This can be tested using ports/minimal and qemu:

    make CC=mips-linux-gnu-gcc-8

Then run with qemu-mips:

    stty raw opost -echo;
    QEMU_LD_PREFIX=/usr/mips-linux-gnu/ qemu-mips build/firmware.elf;
    sleep 1; reset
