* CONTAINS_OP for 'in' and 'is not' tests
* JUMP_IF_NOT_EXC_MATCH for checking exceptions in 'try-except' statements.

Victor Stinner 6193ecd779 Fix a ResourceWarning in generate_opcode_h.py
Use a context manager to close the Python file. Replace also open() with
tokenize.open() to handle coding cookie if any in Lib/opcode.py.

Thomas Wouters 67d8dc1f58 Fix Tools/scripts/generate_opcode_h.py from issue #17861 to work correctly
when building in a separate object tree. More people should build this way.
This may still fail if the source is unwritable, I haven't tested that yet.
