Most clients of _PhysicalFile read the file by translating it into a
Source object using createSource() and then reading it using
FileBasedSource.contentsFromFile, which normalizes newlines using
FileBasedSource.fileReadMode.
However, a few clients read the file directly using
_PhysicalFile.readAsStringSync(), which wasn't doing the
normalization. This CL adds the normalization to that code path.
One such client was the code generation logic for summaries; this
caused code generation to produce different results on Windows, which
led to a test failure.
Fixes#25470.

After inlining, test expectations have changed. A few tests have
starting unexpectedly passing --- this could be because inlining
implements the correct semantics, or the could be passing for the
wrong reason. In any case, the underlying bug in the compiler has not
been fixed.
I will look into all these issues after the Christmas holidays.

Perform a depth-first postorder traversal of the call graph of known
functions. Make an inlining decision based on the vector of argument
types at the call site, and cache inlining decisions. For positive
inlining decisions, cache the optimized function body specialized to
the receiver and argument types at the call site.
Future work:
* Real inlining heuristics.
* Propagate result types of inlined calls.
* Specialized for constant arguments when it makes sense.
* Performance improvements.

This newly introduced test currently fails on the analyzer buildbot due
to transitive import dependencies on
dart_style/lib/src/dart_formatter.dart and
dart_style/lib/src/source_visitor.dart, which have known warnings.

If the JS ast contains an initializer list:
var x = foo(), y = await x;
It would be retained as a single statement and generate invalid output
that awaits 'x' before it has been defined.

This CL reworks the task model grapher (formerly at
pkg/analyzer/tool/task_dependency_graph.dart, now at
pkg/analyzer/tool/task_dependency_graph/generate.dart) so that it
works similarly to the code generation in the analysis server.
Namely, the output file is stored in source control
(pkg/analyzer/tool/task_dependency_graph/tasks.dot), and a test run by
the buildbots verifies that it is up to date. If it is not, the test
outputs the command necessary to update it.
This carries the benefit that:
- Anyone with access to an installation of graphviz can generate the
task model graph easily from its .dot file.
- Any time a change occurs that affects task model dependencies, a
test failure will prompt us that we need to generate a new .dot
file.
- If a change ever occurs that breaks the ability of the task
dependency grapher to produce the graph, a test failure will prompt
us.
The downside is that when making a change that affects task model
dependencies, it is now necessary to re-run the script
pkg/analyzer/tool/task_dependency_graph/generate.dart to avoid a test
failure.
