This CL splits up `Reference.node` in to the most-often fast-case and the
has-to-load case, making the procedure smaller which makes the VM inline
it. This was "verified" by looking at the VMs optimized flow graph for
`Reference.asClass`.
This CL furthermore reduces the number of "calls" to `Reference.node`
by almost half (a reduction of over 3 mio calls when compiling
`compile.dart`) by "caching" the `.node` call in the `as*` methods.
