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 871983d8ae Revert "[VM] Fixes missing bits for new sync* transform." 
This reverts commit 05b7f49c72.

Reason for revert: This appears to break other external targets. Rolling this and original CL back to unblock rolls until deeper investigation can be done.

Clement Skau 05b7f49c72 [VM] Fixes missing bits for new sync* transform. 
The missing part of the transform fixes an issue that manifested
as a crash when running tests for [0].
Which was caused by un-transformed yields in nested functions in sync*s.

The second half of this CL updates the type_checker tool for the new
transform of sync*s.
