Fixes#35966
Add a response property indicating how much of the elapsed time (from
`onMessage` to `doOutput`) was spent in `updateGraph` calls. If there's
no `updateGraph` call, the property is undefined, to save space (with
the downside that it's harder to tell whether a given telemetry event
could have had the property).

It was previously not populated correctly if preserveSymlinks with useSourceOfProjectReference was true,
in that case if module was resolved to symlink and we deduced it refers to source of project reference we want to set "resolvedFileName" correctly

When transforming a module declaration and block, parse tree nodes
contained in the module block have their parent pointers reset due to
`shouldEmitModuleDeclaration` calling into `isInstantiatedModule`, which
needs to set parent pointers to operate.
That causes a crash when later transforming any nodes within the module,
as retrieving their source file in `getSourceFileOfNode` (via
`getOrCreateEmitNode`) fails, due to their new synthesized parent nodes
not being in a source file.
This change avoids the issue by using the parse tree node in `ts.ts` to
decide whether a module declaration should be emitted (i.e. whether the
module contains values).
This means transformers cannot add values to modules that previously did
not contain any.
Fixes#34644.
The word multi-line and multiline are used interchangeably within the file. Multiline seems to be the most used spelling of the word across the TypeScript repository codebase so a few strings have been updated to keep consistency within a single file. Additionally, corrected a minor capitalization mistake.
Msbuild currently uses a combination of `--listFiles` and `--noEmit` to
obtain a list of files to be consumed by tsc. However, these two flags
don't suppress type checking, the results of which msbuild will never
consume. This new switch gives msbuild a faster way to obtain the file
list.
Note: like `--noEmit`, doesn't make sense in build mode.

This intorduces a new symbol-based declaration emitter - currently this
is only used for JSON and JavaScript, as the output is likely worse than

Fixes#33295.
This follows a similar pattern as in #20314 by requiring an explicit
`parent` parameter. Where possible, it uses the appopriate variable at
the call sites.
In several locations there is no context available though (e.g.
inspecting `valueDeclarations`) and we access `.parent` as the code
previously did. From a cursory inspection this seems correct, these
callpaths originate in phases where there must be a `parent` (i.e. in
checker, binder, etc).
Change-Id: I28e4726777b57237bec776e4001e9e69ac591b11
* Add test that fails because file is written multiple times
Reported from #33061
* Handle seenEmittedFiles which was not being set when emit of a file was complete.
It was issue only when errors are reported before emitting (which puts the files into pendingEmit that needs to check only in seenEmittedFiles)
If emit happens before semantic diagnostics query this issue is not repro, because the affected files come into play and those are being set correctly
Fixes#31398
* make baselining source map optional
* Handle emitDeclarationOnly in --build scenario
* Ensure we are using d.ts emit as signature even when --declarationMap is on (map files are emitted before d.ts)

1. Add a script to generate a sorted list of most costly tests. A tests'
cost is roughly `runtime% / number of edits`. A slow test that's only
been updated once is much less valuable than a slow test that has
been updated 20 times: the latter test is catching more changes in the
type system.
2. Check in the results of running this script. I want to make the
skipping behaviour deterministic and the same for everybody, even though
you may get slightly better performance by examining only *your* test
changes.
3. Add code to skip tests until it reaches a 5% chance of missing an
edit. Right now this provides a 38% speedup.
Still not done:
4. Make this value configurable.
5. Make the CI configuration specify a 0% chance of missing an edit.
