This change improves DDC/DDK source maps:
- fix Analyzer backend step locations to pass all of the tests
Kernel was passing. Also improves breakpoints and code coverage.
- fix Analyzer backend to mark hover spans where possible, such as
fields, parameters, locals, `this`, properties, methods, etc.
- refactor DDC/DDK backends to emit source locations, rather than
pointers to Analyzer/Kernel tree nodes.
- unify/simplify source_map_printer between Analyzer/Kernel backends.
- source_map_printer understands JS expression nesting, marking the
innermost JS expression offset corresponding to a given Dart offset.
This preserves hover tooltips, even for expressions with implicit
coercions (e.g. `dart.test(x)`)
- source_map_printer understands that JS end-of-function markings need
to be before the closing brace.
- merge _visitAndMarkExpression and _visitExpression to simplify
Analyzer & Kernel backends.
- fix test expectations where the column location was too specific.
- adds a message to the stepping test runner to help future debugging.
- removes optional destructuring support from Analyzer backend. This
was unused/untested and added complexity. Instead we should decide
if/when to fully switch to destructuring, and then do so.

Also fixes some issues with field initializers; stepping and hover
tooltips should work reasonably now.

This CL "finishes" the first iteration of adding sourcemaps to the
DDC-kernel pipeline. There will likely still be some work left to do,
but it can be added as it is noticed. Ideally by adding a test first.
This CL adds testing and fixes source maps for
- (Better) handling of async, async* and sync*
- Conditional expressions
- await for
- multi catch (catch on (...) { ... } catch on (...) { ... })
- yield
- variable set
- static set
- == and identical
- string concatenation
- is and as
- throw
- map literals

This CL adds source information to the wrapping code for async and named
parameters. This is done for the source mapping not making Chrome (etc)
point to something completely wrong.
Tests are added too.

This CL adds a test for stepping into a constructor with initializers.
It additionally changes the stack map in the kernel pipeline to produce
a better result in this case.

This CL adds a test for stepping over - among others - a reassignment of
a variable with a new named constructor.
It additionally improves the situation in DDC via kernel.

This CL adds the bare minimum of source map generation for the kernel
pipeline in DDC.
It additionally introduces a testing framework that compiles dart files
with DDC (with or without kernel), steps through it via D8 and compares
the positions stopped at to the expected stop positions.
