* chore: add more tests
* chore: move tests around
* chore: make code more clear
* Prefer a likely literal over anonymous type in --noImplicitAny codefixes
Before trying to make an anonymous type for a type's usage, we'll first check if there is exactly one builtin primitive the usage is assignable to, and use it if so. Right now that's only `number` and `string` because `boolean` has no distinguishable members.
A couple of implementation details:
* `tryInsertTypeAnnotation` needed to know to insert a type _after_ a node's `exclamationToken` if it exists
* This code area was written before `??` 😉
* Used unknown/any instead of void when applicable

This fixes two bugs in the parseJSDocCommentWorker().
1. The initial indent was calculated wrongly. It was set to the
difference between the index of the last newline or beginning of file
and the current start marker (position of /**). By calculating it
this way, the newline character itself is counted as indentation
character as well. The initial indent is used as margin for the
whole comment. The margin contains the amount of characters to skip
before the actual content or payload of a comment line. The algorithm
does not skip non-whitespace characters at the beginning of the
content, but it would strip away one whitespace character for
indented content (which does matter, if there is e.g. a Markdown
code block with indentation in the comment).
2. When reducing initial whitespace sequences of comment lines by the
remaining margin the algorithm cut off one character too much. This
might have been introduced to fix 1. It had a similar effect as 1.

Renaming and add test case
Co-authored-by: Andrew Deniszczyc <adeniszczyc@bloomberg.net>
Resolves issue #28031 by overriding default value of
`useNonAdjustedStartPosition` option to replaceNode. Test case included
that confirms intended behaviour.
Use `emit()` for writing `questionDotToken`, leading to properly calling
the emit hooks (which `emitTokenWithComment` doesn't) and printing the
comments. This fixes#35372 by calling its hooks to set the `.__pos`
and `.__end` fields.
Also, remove `getDotOrQuestionDotToken` which was used only here --
mainly because it seems likely to encourage misusing the
`questionDotToken` again.
Also, fix a bunch of `visitor` -> `tokenVisiton` calls in
`visitorPublic.ts`.

* Fix jsdoc comment parsing initial state
Jsdoc comment parsing can be invoked in two modes:
1. top-level parsing, for comments not inside a tag.
2. tag parsing, for comment that occur after the semantic parts of a
tag.
Top-level parsing skips an initial * because it assumes that it is starting
at the very beginning of a JSDoc comment. Tag parsing does not.
The two modes are distinguished by an optional second parameter named
`margin`. When `margin` is provided, it provides an initial indent used
for comment alignment.
Previously, the check for `margin` was a truthy check `if (margin)`.
This check incorrectly treats `margin=""` the same as
`margin=undefined`.
This PR changes the check to `if (margin !== undefined)`, which
correctly treats `margin=""` the same as `margin=" "`.

rename 'PrivateName' to 'PrivateIdentifier'
to match the change of wording in the spec
prposal:
https://tc39.es/proposal-class-fields/#sec-syntax
The rename in the spec was to avoid confusion
between the AST Node PrivateIdentifier
and the internal spec type PrivateName.
So one uses the [[Description]] of a
PrivateIdentifier to look up the PrivateName
for a given scope.
This corresponds closely to our implementation
in the binder and checker:
- we mangle PrivateIdentifier.escapedText to
get a `key` which we use to get the symbol
for a property
f
getLiteralTypeFromProperty-check privateIdentifier
rename and simplify privateNameAndAny test case
make it clearer that all this test is showing is
that we allow accessing arbitrary private identifiers
on `any`.
Note: we could have something more sound here by
checking that there is a private-named field declaration
in a class scope above the property access.

make getPrivateIdentifierPropertyOfType error

Add es2015 target for private name destructured binding test
Add privateNameConstructorSignature test
Add test for navigation bar w private identifier
Remove spurious line from test
// in js file
class A {
exports.#foo = 3; // should error
}
The above line failed to produce an error
when run using the test harness.
When using tsc or the language server,
we got the expected error message.
Removing the troublesome line, as it
seems to say more about the test runner
than about the code it is testing.
Fix inefficient constructor generation
dts: don't emit type for private-identified field
Do not emit types for private-identified fields
when generating declaration files.
// example.ts
export class A {
#foo: number;
}
// example.d.ts
export declare class A {
#foo;
}
**This is not ideal!**
The following would be better:
// example.d.ts
export declare unique class A {
#foo;
}
See discussion:
https://github.com/microsoft/TypeScript/pull/33038#issuecomment-530321165
notice when private-identified field unused
Notice when private-identified fields are unused,
and implement the same behavior as for unused
private-modified fields.
This is used in the language server to make things
grayed out.
This case generates an error when --noUnusedLocals
flag is passed to tsc:
- "<name> is declared but never used"
accept baselines
Revert "dts: don't emit type for private-identified field"
This reverts commit e50305df5fb88121486291abad14478f5339a455.
Instead of just excluding the type from private identifier
emit, only emit a single private identifier
per class.
This accomplishes nominality while
hiding implementation detail that
is irrelevant to .d.ts consumers
only emit a single private identifier in dts
In dts emit, emit at most one private identifier,
and rename it to `#private`.
refactor getPrivateIdentifierPropertyOfType
- safer check for wehther is parse tree node
- return undefined when not found (instead of
a Debug.fail)

Static private identifiers not inherited
Including this in the PR for private
instance fields even though static
private identifiers are banned.
Reason: this change
improves quality of error messages,
see test case.
Thanks Ron!

Thanks Ron!

update diagnostic message 'private identifier'
The nodes for hash private fields are now
called 'private identifier'. Update one last
diagnostic message to use the new terminology.
refine solution for static private identifier fields
- use `continue` instead of `filter` for perf
- better naming
- make it clear the current solution will
need to be altered when we lift the ban on
static private identifier fields, including
a test case that should change in the future
Fix display of private identifiers in lang server
Fix bug where private identifiers in completion
tooltips in the playground were showing up
as the symbol table entries (with underscores and such).
