- PUSH_EXC_INFO pushes an exception sentinel; CHECK_EXC_MATCH keeps it so the
'as <var>' STORE can bind it; POP_TOP discards it for bare handlers.
- Emit 'except <type> as <var>:' and suppress the compiler cleanup
(<var> = None; del <var>).
- WITH_EXCEPT_START no longer aliases SETUP_WITH; it consumes the sentinel so
the with-cleanup never leaks it.
- Detect <setcomp>/<dictcomp> (not just <listcomp>) as comprehensions so
SET_ADD/MAP_ADD reconstruct them for inlining.
Harness: +1, 0 regressions (foundation for multi-except/finally/with).

NODE_RAISE always joined params with commas (Python 2 syntax). For Python 3,
two params is 'raise X from Y'. Harness: +1, 0 regressions; also fixes the
common 'raise X from None' idiom across many files.

SWAP_A was modelled only as tuple-unpack construction, corrupting the stack
for the 3.11 chained-comparison idiom (SWAP n; COPY n). Implement it as a
genuine stack swap via FastStack::swap.
Harness: +17 files (decompilation target: 212→224, stdlib corpus 13->18), 0 regressions.

* Modify .gitignore
* Added support for SWAP and WITH_EXCEPT_START, WITH_EXCEPT_START is simply added on top of SETUP_WITH_A so that it works properly.

The opcode itself is exactly the same as `LOAD_DEREF`
1) The problem is when the class is a closure (e.g. defined inside a function body) then there is a `BUILD_TUPLE` after the `LOAD_BUILD_CLASS` which makes problems.
2) There is another problem which makes the `code->name()` of the class to be part of the function locals. (e.g. `func.<locals>.my_class` instead of `my_class`) which makes the check `srcString->isEqual(code->name().cast<PycObject>())` be invalid.
