Move compiler code out of method verifier.

We want to detect small methods for inlining at the end of
the method verification. Instead of adding more compiler
code to the runtime, we create a callback from the runtime
into the compiler, so that we can keep the code there.
Additionally, we move the compiler-related code that was
already in the method verifier to the compiler since it
doesn't really belong to the runtime in the first place.
