This is take two of #70976. This iteration of the patch makes sure that
custom
diagnostics without any warning group don't get promoted by `-Werror` or
`-Wfatal-errors`.
This implements parts of the extension proposed in
https://discourse.llvm.org/t/exposing-the-diagnostic-engine-to-c/73092/7.
Specifically, this makes it possible to specify a diagnostic group in an
optional third argument.
This reverts commit e39205654dc11c50bd117e8ccac243a641ebd71f.
There are further discussions in
https://github.com/llvm/llvm-project/pull/70976, happening for past two
weeks. Since there were no responses for couple weeks now, reverting
until author is back.
This reverts commit e7f782e7481cea23ef452a75607d3d61f5bd0d22.

I'm involved with the Static Analyzer for the most part.
I think we should embrace newer language standard features and gradually
move forward.
Differential Revision: https://reviews.llvm.org/D154325
This revision fixes typos where there are 2 consecutive words which are
duplicated. There should be no code changes in this revision (only
changes to comments and docs). Do let me know if there are any
undesirable changes in this revision. Thanks.
Adds a `MacroExpansionContext` member to the `AnalysisConsumer` class.
Tracks macro expansions only if the `ShouldDisplayMacroExpansions` is set.
Passes a reference down the pipeline letting AnalysisConsumers query macro
expansions during bugreport construction.

This reverts commit 5663bf201f5c444d6fb56fb1bd471bc53c17d837.
The cyclic dependency problem is addressed now.
This is the ~fifth attempt to land this change.
With this change, we're more or less ready to allow users outside
of the Static Analyzer to take advantage of path diagnostic consumers
for emitting their warnings in different formats.

The AnalyzerOptions object contains too much information that's
entirely specific to the Analyzer. It is also being referenced by
path diagnostic consumers to tweak their behavior. In order for path
diagnostic consumers to function separately from the analyzer,
make a smaller options object that only contains relevant options.

Exactly what it says on the tin! There is no reason I think not to have this.
Also, I added test files for checkers that emit warning under the wrong name.

TableGen and .def files (which are meant to be used with the preprocessor) come
with obvious downsides. One of those issues is that generated switch-case
branches have to be identical. This pushes corner cases either to an outer code
block, or into the generated code.
Inspect the removed code in AnalysisConsumer::DigestAnalyzerOptions. You can see
how corner cases like a not existing output file, the analysis output type being
set to PD_NONE, or whether to complement the output with additional diagnostics
on stderr lay around the preprocessor generated code. This is a bit problematic,
as to how to deal with such errors is not in the hands of the users of this
interface (those implementing output types, like PlistDiagnostics etc).
This patch changes this by moving these corner cases into the generated code,
more specifically, into the called functions. In addition, I introduced a new
output type for convenience purposes, PD_TEXT_MINIMAL, which always existed
conceptually, but never in the actual Analyses.def file. This refactoring
allowed me to move TextDiagnostics (renamed from ClangDiagPathDiagConsumer) to
its own file, which it really deserved.
Also, those that had the misfortune to gaze upon Analyses.def will probably
enjoy the sight that a clang-format did on it.
