Reviewed by Sam Weinig.

Make it so that all capability calculation is funneled through one function, which tells
you everything you wanted to know: can it be inlined, and can it be compiled.

This work will help with https://bugs.webkit.org/show_bug.cgi?id=116557, since now the
JIT has a fairly authoritative answer to the "can it be inlined" question.
