GH-96421: Insert shim frame on entry to interpreter (GH-96319)
* Adds EXIT_INTERPRETER instruction to exit PyEval_EvalDefault()

* Simplifies RETURN_VALUE, YIELD_VALUE and RETURN_GENERATOR instructions as they no longer need to check for entry frames.

bpo-46841: Quicken code in-place (GH-31888)
* Moves the bytecode to the end of the corresponding PyCodeObject, and quickens it in-place.

* Removes the almost-always-unused co_varnames, co_freevars, and co_cellvars member caches

* _PyOpcode_Deopt is a new mapping from all opcodes to their un-quickened forms.

* _PyOpcode_InlineCacheEntries is renamed to _PyOpcode_Caches

* _Py_IncrementCountAndMaybeQuicken is renamed to _PyCode_Warmup

* _Py_Quicken is renamed to _PyCode_Quicken

* _co_quickened is renamed to _co_code_adaptive (and is now a read-only memoryview).

* Do not emit unused nonzero opargs anymore in the compiler.

bpo-45316: Move private PyCode C API to internal C API (GH-31576)
Rename private functions (no exported), add an underscore prefix:

* PyLineTable_InitAddressRange() => _PyLineTable_InitAddressRange()
* PyLineTable_NextAddressRange() => _PyLineTable_NextAddressRange()
* PyLineTable_PreviousAddressRange() => _PyLineTable_PreviousAddressRange()

Move private functions to the internal C API:

* _PyCode_Addr2EndLine()
* _PyCode_Addr2EndOffset()
* _PyCode_Addr2Offset()
* _PyCode_InitAddressRange()
* _PyCode_InitEndAddressRange(
* _PyLineTable_InitAddressRange()
* _PyLineTable_NextAddressRange()
* _PyLineTable_PreviousAddressRange()

No longer export the following internal functions:

* _PyCode_GetVarnames()
* _PyCode_GetCellvars()
* _PyCode_GetFreevars()
* _Py_GetSpecializationStats()

Add "extern" to pycore_code.h functions to identify them more easiliy
(they are still not exported).

Fix a SystemError in code.replace() (#27771)
While the comment said 'We don't bother resizing localspluskinds',
this would cause .replace() to crash when it happened.
(Also types.CodeType(), but testing that is tedious, and this tests all
code paths.)

bpo-43950: Add code.co_positions (PEP 657) (GH-26955)
This PR is part of PEP 657 and augments the compiler to emit ending
line numbers as well as starting and ending columns from the AST
into compiled code objects. This allows bytecodes to be correlated
to the exact source code ranges that generated them.

This information is made available through the following public APIs:

* The `co_positions` method on code objects.
* The C API function `PyCode_Addr2Location`.
