Since you're switching to the native tests, you should add #ifdef's in this file
to run the tests for the opcodes you implement in this CL. These should be
similar to the #ifdef's already there for x64.

In the file tests for my implemented opcodes are by-default on, so there's no
need to add #ifdef's this time. I will remember to add them when I add opcodes
in the future.

That's right. OK
