This PR adds a scheduling model for the i7200 processor based on this implementation in GCC:
https://github.com/MediaTek-Labs/gcc/blob/mips/umips/gcc6_v12/gcc/config/mips/i7200.md

The new model replaces the generic one when -mcpu=i7200 is set.

The model is based on the GCC machine description for i7200 and replaces
the generic model when -mcpu=i7200.

To use this model the machine scheduler has to be enabled. This can be done by passing the -mllvm -enable-misched flag which will run the pre-RA scheduler. Optionally, to also run the post-RA machine scheduler -mllvm -misched-postra should be set as well.
