Current implementation is fully compatible with existing dwarf.  There
are plans and code to represent value expressions as well, for variables
that are no longer available but whose value can still be computed, but
since we can't quite represent them in Dwarf, we currently discard such
expressions.

VTA is pretty much ready for integration, nbut it still requires buy-in
from global maintainers.
