yoff 558cd5b00c Python: test dead bindings under no-raise CFG abstraction ...

Adds 'dead_under_no_raise.py' to the bindings test suite, capturing the
three CPython patterns where bindings legitimately have no CFG node
because the surrounding code is unreachable under the 'no expressions
raise' abstraction:

  1. Statements after a 'try: return X; except: pass' block.
  2. The 'else:' clause of a try whose body always raises.
  3. Cache-lookup pattern 'try: return cache[k]; except: pass' followed
     by computation and store.

These bindings intentionally carry no 'cfgdefines=' annotations. If
raise modelling is later added to the CFG, the BindingsTest will surface
the new CFG nodes as unexpected results and this file will need to be
revisited.
