Fix #546: Add support to run partest with fullOpt
Add hints for the (future) optimizer in method info.

The hints are:
* whether the method is an accessor (getter or setter)
* whether it has the @inline annotation

These information are currently unused, but the (future) inlining
optimizer might use them as heuristics. Since this is a binary
incompatible change, it had better be added now.
Fix #545: Inline reflective call proxy for Array.update
Fix #543: Incremental optimizer would never really invalidate.

When the file changes, the dce would invalidate its info and
its desugared version, but not its tree. So it would recompute
the desugared version from ... the old tree.
