Run tests in parallel or only some with a filter

[Levak]

I rewrote the all_tests.sh file to spread all tests among a set amount of workers so that it runs faster on machines with lots of cores. And since I was also trying to make some fixes in pycdc I needed to run only some tests of the fixtures I was touching.

make check JOBS=4 will spawn 4 workers and spread the tests among them.
make check FILTER=try will only run tests that contain try in their name.

I think its may be good to have the option to test certain tests, but I also think that after every change, all tests should be checked, because sometimes things rely on each other and you may broke other things accidentally

Yes, I totally agree with you on "a change in the code should be tested against all tests", but from my POV, in this project, when you're trying to implement one opcode, it rarely breaks others, besides, you just want to quickly check if it works with the intended test, and then run all tests to make sure you didn't break everything.
