[tools] add an experimental script for bisecting parrot

You can use it to automatically rebuild rakudo and run it against a test file
when bisecting parrot. Call it as

    $ git bisect run ../tools/bisect-parrot.pl test-file.t

Assuming that test-file.t returns with a non-zero exit status if it fails
