JIT: Fix crash due to incorrect caching on side exits when exiting jitted code.
* Make sure that stack is in correct state at side exits with TOS cached values
* Simplify choice of cached items for side exits
Make the attributes in _bz2 module thread-safe on the free-threading build.
Attributes (eof, needs_input, unused_data) are now stored atomically or
accessed via mutex-protected getters.
This combines most _PyStackRef functions and macros between the free
threaded and default builds.
- Remove Py_TAG_DEFERRED (same as Py_TAG_REFCNT)
- Remove PyStackRef_IsDeferred (same as !PyStackRef_RefcountOnObject)

When a `str` is encoded in `bytearray.__init__` the encoder tends to
create a new unique bytes object. Rather than allocate new memory and
copy the bytes use the already created bytes object as bytearray
backing. The bigger the `str` the bigger the saving.
Mean +- std dev: [main_encoding] 497 us +- 9 us -> [encoding] 14.2 us +- 0.3 us: 34.97x faster
```python
import pyperf
runner = pyperf.Runner()
runner.timeit(
name="encode",
setup="a = 'a' * 1_000_000",
stmt="bytearray(a, encoding='utf8')")
```
We need to use release/acquire ordering for the 'mask' member of the set
structure. Without this, `set_lookkey_threadsafe()` could be looking at
the old value of `table` but the new value of `mask`.
