Attempt to speed up deepfreeze.py (#107887)
* Instead of calling get_identifiers_and_strings(), extract identifiers and strings from pycore_global_strings.h.
* Avoid ast.literal_eval(), it's very slow.

gh-101524: Only Use Public C-API in the _xxsubinterpreters Module (gh-107359)
The _xxsubinterpreters module should not rely on internal API.  Some of the functions it uses were recently moved there however.  Here we move them back (and expose them properly).

gh-75371: reformat Makefile.pre.in to accommodate for empty FRAMEWORKALTINSTALLLAST (#107035)
in the case of an empty FRAMEWORKALTINSTALLLAST, this patch prevents leaving
an astray linebreak and two tabs in the resulting Makefile.

Before change:
```
.PHONY: commoninstall
commoninstall:  check-clean-src  \
		altbininstall libinstall inclinstall libainstall \
		sharedinstall altmaninstall \

```

After change (with empty FRAMEWORKALTINSTALLLAST):
```
.PHONY: commoninstall
commoninstall:  check-clean-src  \
		altbininstall libinstall inclinstall libainstall \
		sharedinstall altmaninstall
```

gh-106529: Fix subtle Tier 2 edge case with list iterator (#106756)
The Tier 2 opcode _IS_ITER_EXHAUSTED_LIST (and _TUPLE)
didn't set it->it_seq to NULL, causing a subtle bug
that resulted in test_exhausted_iterator in list_tests.py
to fail when running all tests with -Xuops.

The bug was introduced in gh-106696.

Added this as an explicit test.

Also fixed the dependencies for ceval.o -- it depends on executor_cases.c.h.

Restore previous behavior of 'make regen-cases' (#106541)
When running 'make regen-cases' just to check whether anything changed,
it's annoying that even if nothing changes, the output files are touched,
causing an expensiv rebuild of _bootstrap_python and anything it creates.

So use  consistently for all output files.

gh-106290: Fix edge cases around uops (#106319)
- Tweak uops debugging output
- Fix the bug from gh-106290
- Rename `SET_IP` to `SAVE_IP` (per https://github.com/faster-cpython/ideas/issues/558)
- Add a `SAVE_IP` uop at the start of the trace (ditto)
- Allow `unbound_local_error`; this gives us uops for `LOAD_FAST_CHECK`, `LOAD_CLOSURE`, and `DELETE_FAST`
- Longer traces
- Support `STORE_FAST_LOAD_FAST`, `STORE_FAST_STORE_FAST`
- Add deps on pycore_uops.h to Makefile(.pre.in)

gh-104584: Baby steps towards generating and executing traces (#105924)
Added a new, experimental, tracing optimizer and interpreter (a.k.a. "tier 2"). This currently pessimizes, so don't use yet -- this is infrastructure so we can experiment with optimizing passes. To enable it, pass ``-Xuops`` or set ``PYTHONUOPS=1``. To get debug output, set ``PYTHONUOPSDEBUG=N`` where ``N`` is a debug level (0-4, where 0 is no debug output and 4 is excessively verbose).

All of this code is likely to change dramatically before the 3.13 feature freeze. But this is a first step.

gh-104692: Include commoninstall as a prerequisite for bininstall (#104693)
This ensures that `commoninstall` is completed before `bininstall` is
started when parallel builds are used (`make -j install`), and so the
`python3` symlink is only installed after all standard library modules
are installed.

gh-101282: Apply BOLT optimizations to libpython for shared builds (#104709)
Apply BOLT optimizations to libpython for shared builds. Most of the C
code is in libpython so it is critical to apply BOLT there fully realize
BOLT benefits.

This change also reworks how BOLT instrumentation is applied. It
effectively removes the readelf based logic added in gh-101525 and
replaces it with a mechanism that saves a copy of the pre-bolt binary
and restores that copy when necessary. This allows us to perform BOLT
optimizations without having to manually delete the output binary to
force a new bolt run.

Also:
- add a clean-bolt target for purging BOLT files and hook that up to the
  clean target
- .gitignore BOLT related files

Before and after this refactor, `make` will no-op after a previous run.
Both versions should also share common make DAG deficiencies where
targets fail to trigger as often as they need to or can trigger
prematurely in certain scenarios. e.g. after this change you may need to
`rm profile-bolt-stamp` to force a BOLT run because there aren't
appropriate non-phony targets for BOLT's make target to depend on.

To make it easier to iterate on custom BOLT settings, the flags to pass
to instrumentation and application are now defined in configure and can
be overridden by passing BOLT_INSTRUMENT_FLAGS and BOLT_APPLY_FLAGS.

- Compiler and interpreter changes to support the new syntax and scoping rules

gh-104490: Consistently define phony make targets (#104491)
By convention make targets that don't refer to a file have a dependency
on the fake .PHONY target/file. This ensures that these targets are
always evaluated because there is no rule to create a .PHONY file
and that will force make to think the rule is out of date and needs
to be rebuilt.

This commit consistently associates virtual targets with .PHONY by
declaring the .PHONY dependency immediately above the make rule. This
should avoid race conditions and avoidable rebuilds across multiple make
invocations.

gh-99108: Replace SHA3 implementation HACL* version (#103597)
Replaces our built-in SHA3 implementation with a verified one from the HACL* project.

This implementation is used when OpenSSL does not provide SHA3 or is not present.

3.11 shiped with a very slow tiny sha3 implementation to get off of the <=3.10 reference implementation that wound up having serious bugs. This brings us back to a reasonably performing built-in implementation consistent with what we've just replaced our other guaranteed available standard hash algorithms with: code from the HACL* project.

gh-100227: Only Use deepfreeze for the Main Interpreter (gh-103794)
Deep-frozen code objects are cannot be shared (currently) by
interpreters, due to how adaptive specialization can modify the
bytecodes. We work around this by only using the deep-frozen objects in
the main interpreter. This does incur a performance penalty for
subinterpreters, which we may be able to resolve later.
