Add a copied flag to virtual frame elements that tells if a copy has
...
been made of the element. Set it when copying an element, clear it
when writing to an element marked copied and discovering that it is
not copied.
The copied flags on entry frames are exact. Preparing a frame for
merging set the copied flags to be exact (to increase the likelihood
of matching the entry frame or another frame).

Add a bit to a virtual frame element telling if it's been copied. Set
...
it when a copy is made, clear it when the element is next written.

Fix issue 265 by handling extra statement state on the frame based on
...
the expectation at the break, continue, and return labels (including
shadowed ones) instead of based on the AST nodes.

Before emitting code to merge frames, forget the sync flag (telling
...
that an element is mirrored in memory) for elements whose target is a
register. This avoids generating some duplicate merge blocks.
