I did a few things wrong with registers on armv7 in the css jit.  This not only passes the tests, but it doesn't crash when running https://www.webkit.org/blog-files/css-jit-introduction/html5-single-page-microbenchmark.html

Also, I'm not sure that my register allocation in modulo for arm64 and armv7 is counted correctly.  Does this need to be changed somewhere, too?
