Dmitry Stefantsov c191551fac [cfe] Remove BottomType

Johnni Winther 56f46b0659 Remove non-nullable experiment flag from front_end test cases. 
This changes the CFE expectation test suites to use unsound null safety
as default to avoid passing --enable-experiments=no-non-nullable to opt
out old test folders.

This change removes most test folders from the 'strong' tester, since
this now only supports sound null safety, which requires all libraries
to be opted in. Instead, the 'weak' tester now runs all test folders.
Additionally the 'outline' tester is changed to use unsound null safety
so that it call be used on all test folders.

The 'fast_strong' tester is removed since it should just be run locally
and it can be run by passing an option to the other testers.

References to non-existing 'shaker' folder has been removed from
testing.json.

Clement Skau 2359f4dc68 [VM] Reworked: Remove unnecessary Closure.clone() from sync*. 
Removes the Closure.clone() in sync* by adding an additional closure
around the rewritten sync* function body.

This is a re-worked version of the now reverted:
- https://dart-review.googlesource.com/c/sdk/+/136190
- https://dart-review.googlesource.com/c/sdk/+/144948

This CL includes changes from both the above CLs, in addition to:
- A new 'ShadowRewriter' transformer to do deep rewriting of
  shadowed parameters.
  Previous versions only rewrote the immediate sync* function, missing
  references in nested rewritten functions.

Note: This CL is re-landing largely unchanged since the roll-blocking
issues suspected to be caused by this was later attributed to a
different set of changes.
I have independently re-run all failing external tests to verify
them passing for this CL.

Clement Skau ca94ad7112 [VM] Remove unnecessary Closure.clone() from sync*. 
Instead, this CL wraps sync*'s sync_op in an additional function
that captures local copies of the necessary closure state.
Notably this state includes the parameters of the original sync* function
as these also need to be cloned for each instance.


Note: a large number of .expect files have a small number of changes
due to the additional wrapper function, as well as some extra plumbing.

which we should look into recovering by having better inlining heuristics.
