gh-111520: Integrate the Tier 2 interpreter in the Tier 1 interpreter (#111428)
- There is no longer a separate Python/executor.c file.
- Conventions in Python/bytecodes.c are slightly different -- don't use `goto error`,
  you must use `GOTO_ERROR(error)` (same for others like `unused_local_error`).
- The `TIER_ONE` and `TIER_TWO` symbols are only valid in the generated (.c.h) files.
- In Lib/test/support/__init__.py, `Py_C_RECURSION_LIMIT` is imported from `_testcapi`.
- On Windows, in debug mode, stack allocation grows from 8MiB to 12MiB.
- **Beware!** This changes the env vars to enable uops and their debugging
  to `PYTHON_UOPS` and `PYTHON_LLTRACE`.

gh-109979: Auto-generate the target for DEOPT_IF() (#110193)
In Python/bytecodes.c, you now write
```
    DEOPT_IF(condition);
```
The code generator expands this to
```
    DEOPT_IF(condition, opcode);
```
where `opcode` is the name of the unspecialized instruction.
This works inside macro expansions too.

**CAVEAT:** The entire `DEOPT_IF(condition)` statement must be on a single line.
If it isn't, the substitution will fail; an error will be printed by the code generator
and the C compiler will report some errors.

gh-109295: Skip test_generated_cases if different mount drives (#109308)
On Windows, skip the test if the current working directory and the
Python source code directory have different mount drives. It happens
if the temporary directory is on a different mount drive than the
Python source code.

gh-106581: Support multiple uops pushing new values (#108895)
Also avoid the need for the awkward .clone() call in the argument
to mgr.adjust_inverse() and mgr.adjust().

gh-106812: Refactor cases_generator to allow uops with array stack effects (#107564)
Introducing a new file, stacking.py, that takes over several responsibilities related to symbolic evaluation of push/pop operations, with more generality.

Thoroughly refactor the cases generator (#107151)
This mostly extracts a whole bunch of stuff out of generate_cases.py into separate files, but there are a few other things going on here.

- analysis.py: `Analyzer` etc.
- instructions.py: `Instruction` etc.
- flags.py: `InstructionFlags`, `variable_used`, `variable_used_unspecialized`
- formatting.py: `Formatter` etc.
- Rename parser.py to parsing.py, to avoid conflict with stdlib parser.py
- Blackify most things
- Fix most mypy errors
- Remove output filenames from Generator state, add them to `write_instructions()` etc.
- Fix unit tests
