To nest well if another similar transformation has been done. we must
ensure that any existing top level TryCatchBlock comes first. Otherwise
our TryCatchBlock would have higher precedence, and other catch blocks
would be skipped.

<p>
This is the reason for the delayed generateEntryBlock*() calls.
Unfortunately, this considerably adds to the complexity of this adapter.
