c3c Implement MIPS3 target support

It would be nice to have mips-3 support for some homebrew platforms like n64 or some modems.

Im not sure if this could be a good reference: https://github.com/llvm/llvm-project/issues/18632

How would we test it?

Thats a good question, i can setup a few n64 and router firmware tests or an example program

I will probably want to test it from MacOS, are there any easy helpers to do that?

Wdym by helper 0:?

Software that will help you run and emulate MIPS3 code on MacOS.

Ohh, you could try ares which is an n64 emulator or an irix emulator https://forums.irixnet.org/thread-1012-post-7165.html

Looks non-trivial. Is there a way to bring this to CI?

Yeah i think, my other idea was to use something like this https://github.com/gioannides/MIPS_SIMULATOR/tree/master, seems to be smaller than using a full emulator
