This makes IndentedScope the single point where we can print additional info in
the future, like e.g. AST IDs (at least when the TODOs are fixed). Minor other

This CL adds machinery to unwind stack handlers from the stack and store
them into a generator's operand array.  It also includes routines to
reinstate them.  Together this allows generators to yield within
try/catch and try/finally blocks.

Do not change environment between simulate and scope with no observable side-effects in HandlePropertyAssignment.

LChunkBuilder reconstructs the environment by applying simulates. A scope with no observable side-effects has no simulates. If the scope deoptimizes, then LChunkBuilder would miss the changes to the environment between the last simulate and the scope.
