Logan Smith 715c72b4fb [NFC][analyzer] Return underlying strings directly instead of OS.str()
This avoids an unnecessary copy required by 'return OS.str()', allowing
instead for NRVO or implicit move. The .str() call (which flushes the
stream) is no longer required since 65b13610a5,
which made raw_string_ostream unbuffered by default.

Artem Dergachev 7309359928 [analyzer] Fix scan-build report deduplication.
The previous behavior was to deduplicate reports based on md5 of the
html file. This algorithm might have worked originally but right now
HTML reports contain information rich enough to make them virtually
always distinct which breaks deduplication entirely.

The new strategy is to (finally) take advantage of IssueHash - the
stable report identifier provided by clang that is the same if and only if
the reports are duplicates of each other.

Additionally, scan-build no longer performs deduplication on its own.
Instead, the report file name is now based on the issue hash,
and clang instances will silently refuse to produce a new html file
when a duplicate already exists. This eliminates the problem entirely.

The '-analyzer-config stable-report-filename' option is deprecated
because report filenames are no longer unstable. A new option is
introduced, '-analyzer-config verbose-report-filename', to produce
verbose file names that look similar to the old "stable" file names.
The old option acts as an alias to the new option.

Valeriy Savchenko 9e02f58780 [analyzer] Highlight arrows for currently selected event
In some cases, when the execution path of the diagnostic

Valeriy Savchenko 97bcafa28d [analyzer] Add control flow arrows to the analyzer's HTML reports
This commit adds a very first version of this feature.
It is off by default and has to be turned on by checking the
corresponding box.  For this reason, HTML reports still keep
control notes (aka grey bubbles).

Further on, we plan on attaching arrows to events and having all arrows
not related to a currently selected event barely visible.  This will
help with reports where control flow goes back and forth (eg in loops).
Right now, it can get pretty crammed with all the arrows.

Duncan P. N. Exon Smith af4fb416bd clang/StaticAnalyzer: Stop using SourceManager::getBuffer
Update clang/lib/StaticAnalyzer to stop relying on a `MemoryBuffer*`,
using the `MemoryBufferRef` from `getBufferOrNone` or the
`Optional<MemoryBufferRef>` from `getBufferOrFake`, depending on whether
there's logic for checking validity of the buffer. The change to
clang/lib/StaticAnalyzer/Core/IssueHash.cpp is potentially a
functionality change, since the logic was wrong (it checked for
`nullptr`, which was never returned by the old API), but if that was
reachable the new behaviour should be better.

Kirstóf Umann fe1a3a7e8c [analyzer] Change the default output type to PD_TEXT_MINIMAL in the frontend, error if an output loc is missing for PathDiagConsumers that need it
The title and the included test file sums everything up -- the only thing I'm
mildly afraid of is whether anyone actually depends on the weird behavior of
HTMLDiagnostics pretending to be TextDiagnostics if an output directory is not

Kirstóf Umann 7bf871c39f [analyzer][NFC] Move the text output type to its own file, move code to PathDiagnosticConsumer creator functions
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.

Kristof Umann 72649423c0 [analyzer][NFC] Fix inconsistent references to checkers as "checks"
Traditionally, clang-tidy uses the term check, and the analyzer uses checker,
but in the very early years, this wasn't the case, and code originating from the
early 2010's still incorrectly refer to checkers as checks.

This patch attempts to hunt down most of these, aiming to refer to checkers as
checkers, but preserve references to callback functions (like checkPreCall) as
checks.

A condition could be a multi-line expression where we create the highlight

it cannot be added to multiple lines because we have only one ending part
which contains all the notes. So that it cannot have multiple endings and
therefore this patch narrows down the ranges of the highlight to the given
interesting variable of the condition. It prevents HTML-breaking injections.

We understand that people may be surprised that we're moving the header

Foundation's lawyer and we believe this is the correct approach.

Essentially, all code in the project is now made available by the LLVM

Kristof Umann 549f9cd46f [analyzer] Evaluate all non-checker config options before analysis
In earlier patches regarding AnalyzerOptions, a lot of effort went into
gathering all config options, and changing the interface so that potential
misuse can be eliminited.

Up until this point, AnalyzerOptions only evaluated an option when it was
querried. For example, if we had a "-no-false-positives" flag, AnalyzerOptions
would store an Optional field for it that would be None up until somewhere in
the code until the flag's getter function is called.

However, now that we're confident that we've gathered all configs, we can
evaluate off of them before analysis, so we can emit a error on invalid input
even if that prticular flag will not matter in that particular run of the
analyzer. Another very big benefit of this is that debug.ConfigDumper will now
show the value of all configs every single time.

Also, almost all options related class have a similar interface, so uniformity
is also a benefit.

The implementation for errors on invalid input will be commited shorty.
