Rework IR code generation for try/catch/finally

Simplify the generated code. Add a special block to catch
exceptions thrown inside a catch() statement.

store the exception on the stack when entering finally and
rethrow it at the end. This ensure correct behavior for
break/continue/return statements inside finally.

Don't check for exceptions after calling push_catch_scope
and pop_scope in the JIT'ed code. This can lead to infinite
loops when throwing inside an exception handler.
