gh-118335: Configure Tier 2 interpreter at build time (#118339)
The code for Tier 2 is now only compiled when configured
with `--enable-experimental-jit[=yes|interpreter]`.

We drop support for `PYTHON_UOPS` and -`Xuops`,
but you can disable the interpreter or JIT
at runtime by setting `PYTHON_JIT=0`.
You can also build it without enabling it by default
using `--enable-experimental-jit=yes-off`;
enable with `PYTHON_JIT=1`.

On Windows, the `build.bat` script supports
`--experimental-jit`, `--experimental-jit-off`,
`--experimental-interpreter`.

In the C code, `_Py_JIT` is defined as before
when the JIT is enabled; the new variable
`_Py_TIER2` is defined when the JIT *or* the
interpreter is enabled. It is actually a bitmask:
1: JIT; 2: default-off; 4: interpreter.

README

This directory contains a number of Python programs that are useful
while building or extending Python.

build           Automatically generated directory by the build system
                contain build artifacts and intermediate files.

buildbot        Batchfiles for running on Windows buildbot workers.

c-analyzer      Tools to check no new global variables have been added.

cases_generator Tooling to generate interpreters.

clinic          A preprocessor for CPython C files in order to automate
                the boilerplate involved with writing argument parsing
                code for "builtins".

freeze          Create a stand-alone executable from a Python program.

gdb             Python code to be run inside gdb, to make it easier to
                debug Python itself (by David Malcolm).

i18n            Tools for internationalization. pygettext.py
                parses Python source code and generates .pot files,
                and msgfmt.py generates a binary message catalog
                from a catalog in text format.

importbench     A set of micro-benchmarks for various import scenarios.

msi             Support for packaging Python as an MSI package on Windows.

nuget           Files for the NuGet package manager for .NET.

patchcheck      Tools for checking and applying patches to the Python source code
                and verifying the integrity of patch files.

peg_generator   PEG-based parser generator (pegen) used for new parser.

scripts         A number of useful single-file programs, e.g. run_tests.py
                which runs the Python test suite.
