This adds 2 new hints `NULL_AWARE_BEFORE_OPERATOR` and `NULL_AWARE_IN_LOGICAL_OPERATOR`.
The previous `NULL_AWARE_IN_CONDITION` hint didn't catch null-aware issues in assigments or expression statements with logical operators. `NULL_AWARE_IN_LOGICAL_OPERATOR` handles those cases.
`NULL_AWARE_BEFORE_OPERATOR` handle issue like `a?.b + c`.

This reverts commit 09eed74a8a.
Reason for revert: Too much SDK code is not yet compliant.
Original change's description:
> Make `void` a static warning to use almost everywhere.
>
> Changed the hint to a StaticWarningCode, since that's the new spec'd
> error type and the hint is no longer needed.
>
> Added a new set of methods to test the cases.
>
> Didn't try to solve the problem generally ("all usages except ... are
> errors" means it easier, in theory, to make a ReportVoidExpressions
> style visitor that catches absolutely all types) because most of the
> work is actually about suppressing errors that are no longer needed.
> Ie, from NO_SUCH_METHOD to USAGE_OF_VOID_RESULT which means we have to
> put the void handling logic into each AST method specially anyway.
>
> Some redundant tests removed.
>
> Don't flag: ternaries, void -> void assignments, void returns in
> dynamic.

This follows Leaf's simplified suggestion. As a temporary hack it
assumes that the mixin passes its type parameters through to its
superclass constraint unchanged.

This warning fires if a top level initializer depends on the type of a
method whose type is subject to type inference. This warning is
needed because the analyzer implementation of top level type inference
doesn't guarantee that the method type will be inferred prior to the
initializer, so it's possible that type inference will produce an
incorrect result. See #31925 for more details.

The displayName of an anonymous closure is a blank String, resulting in messages like:
[error] The return type 'String' is not a 'int', as defined by the method ''.
After this change, an error might instead look like:
$ xcodebuild/ReleaseX64/dart-sdk/bin/dartanalyzer --strong 26056.dart
Analyzing 26056.dart...

The analyzer used to emit a warning when a type parameter to a generic
method was used in an "is" check. This warning was there to help
users write code that worked correctly on both Dart 1.0 and 2.0. Now
that 2.0 generic methods are being more broadly supported and used,
this warning is blocking further library work, and is being removed.

In particular, enforce that a method annotated with @visibleForTesting can only
be referenced from within the declaring library, or within a file that has
"/test" in its path. This allows @visibleForTesting methods to be accessed from
test files, or files in "/testing" folders, etc.

Rather than have multple fine grained error codes for each type
of modifier in each situation, this CL adds a new analyzer
ParserErrorCode.EXTRANEOUS_MODIFIER parallel to the fast parser
error code and updates the AstBuilder to generate that error
rather than ParserErrorCode.ABSTRACT_CLASS_MEMBER.
My goal is to review each analyzer error code similar to
ParserErrorCode.ABSTRACT_CLASS_MEMBER and map each to the same
ParserErrorCode.EXTRANEOUS_MODIFIER error code.

This CL is identical to the reverted CL 2990703002 which implements
syntactic support for generalized void in the analyzer, plus two bug
fixes in pkg/analyzer/test/generated/parser_test.dart and
pkg/analyzer_cli/test/error_test.dart. In the former, a test on parsing
`void,` was changed to expect an error: _isTypeIdentifier on a lone
`void` will no longer return true, which is necessary because `void`
can now be used as a type annotation alone. Another test on `void x`
was added, which produces the behavior previously seen for `void,`.
In error_test, the error which is used throughout was changed from
`void foo;` to `var int foo;` (because the former is no longer an
error).
Review-Url: https://codereview.chromium.org/2992623002 .
Changed the analyzer parser to accept usages of `void` which were
previously rejected as syntax errors: `void` can now be the type
annotation for a variable or parameter, and it can be an actual type
argument.
Removed affected error codes like VOID_PARAMETER, VOID_VARIABLE,
VOID_RETURN_FOR_GETTER and associated declarations (like checking
functions), and adjusted test cases to expect success rather than
compile time errors.
Adjusted generalized_void_syntax_test.dart (it had real errors like
`final` variables with no initializer etc. that were not detected
when tools would just reject the file as syntactically wrong).
