bpo-39791 native hooks for importlib.resources.files (GH-20576)
* Provide native .files support on SourceFileLoader.

* Add native importlib.resources.files() support to zipimporter. Remove fallback support.

* make regen-all

* 📜🤖 Added by blurb_it.

* Move 'files' into the ResourceReader so it can carry the relevant module name context.

* Create 'importlib.readers' module and add FileReader to it.

* Add zip reader and rely on it for a TraversableResources object on zipimporter.

* Remove TraversableAdapter, no longer needed.

* Update blurb.

* Replace backslashes with forward slashes.

* Incorporate changes from importlib_metadata 2.0, finalizing the interface for extension via get_resource_reader.

bpo-39156: Break up COMPARE_OP into four logically distinct opcodes. (GH-17754)
Break up COMPARE_OP into four logically distinct opcodes:
* COMPARE_OP for rich comparisons
* IS_OP for 'is' and 'is not' tests
* CONTAINS_OP for 'in' and 'is not' tests
* JUMP_IF_NOT_EXC_MATCH for checking exceptions in 'try-except' statements.

Produce cleaner bytecode for 'with' and 'async with' by generating separate code for normal and exceptional paths. (#6641)
Remove BEGIN_FINALLY, END_FINALLY, CALL_FINALLY and POP_FINALLY bytecodes. Implement finally blocks by code duplication.
Reimplement frame.lineno setter using line numbers rather than bytecode offsets.

bpo-37213: Handle negative line deltas correctly in the peephole optimizer (GH-13969)
The peephole optimizer was not optimizing correctly bytecode after negative deltas were introduced. This is due to the fact that some special values (255) were being searched for in both instruction pointer delta and line number deltas.

bpo-31241: Fix AST node position for list and generator comprehensions. (GH-10633)
The lineno and col_offset attributes of AST nodes for list comprehensions,
generator expressions and tuples are now point to the opening parenthesis or
square brace. For tuples without parenthesis they point to the position
of the first item.

INADA Naoki c2e1607a51 bpo-34100: Merge constants recursively (GH-8341)
There are some same consts in a module.  This commit merges them into
single instance.  It reduces number of objects in memory after loading modules.

Elvis Pranskevichus a6e956bcb0 bpo-34726: Fix handling of hash-based pycs in zipimport. (GH-10327)
Current support for hash-based bytecode files in `zipimport` is rather
sparse, which leads to test failures when the test suite is ran with
the ``SOURCE_DATE_EPOCH`` environment variable set.

This teaches zipimport to handle hash-based pycs properly.
