Aaron Puchert 1cb15b10ea Correct Doxygen syntax for inline code
There is no syntax like {@code ...} in Doxygen, @code is a block command
that ends with @endcode, and generally these are not enclosed in braces.
The correct syntax for inline code snippets is @c <code>.

[clang][nearly-NFC] Remove some superfluous uses of NamedDecl::getNameAsString
`OS << ND->getDeclName();` is equivalent to `OS << ND->getNameAsString();`
without the extra temporary string.

This is not quite a NFC since two uses of `getNameAsString` in a
diagnostic are replaced, which results in the named entity being
quoted with additional "'"s (ie: 'var' instead of var).

Denys Petrov 86e1b73507 [analyzer] Simplify function SVal::getAsSymbolicExpression and similar ones
Summary: Simplify functions SVal::getAsSymbolicExpression SVal::getAsSymExpr and SVal::getAsSymbol. After revision I concluded that `getAsSymbolicExpression` and `getAsSymExpr` repeat functionality of `getAsSymbol`, thus them can be removed.

Fix: Remove functions SVal::getAsSymbolicExpression and SVal::getAsSymExpr.

Kirstóf Umann 5192783bb2 [analyzer][RetainCount] Tie diagnostics to osx.cocoa.RetainCount rather then RetainCountBase, for the most part
Similarly to other patches of mine, I'm trying to uniformize the checker
interface so that dependency checkers don't emit diagnostics. The checker that
made me most anxious so far was definitely RetainCount, because it is definitely
impacted by backward compatibility concerns, and implements a checker hierarchy
that is a lot different to other examples of similar size. Also, I don't have
authority, nor expertise regarding ObjC related code, so I welcome any
objection/discussion!

Benjamin Kramer adcd026838 Make llvm::StringRef to std::string conversions explicit.
This is how it should've been and brings it more in line with
std::string_view. There should be no functional change here.

This is mostly mechanical from a custom clang-tidy check, with a lot of
manual fixups. It uncovers a lot of minor inefficiencies.

This doesn't actually modify StringRef yet, I'll do that in a follow-up.

Artem Dergachev 6b85f8e99b [analyzer] NFC: Move getStmt() and createEndOfPath() out of PathDiagnostic.
These static functions deal with ExplodedNodes which is something we don't want
the PathDiagnostic interface to know anything about, as it's planned to be
moved out of libStaticAnalyzerCore.

Artem Dergachev 2f169e7cdd [analyzer] NFC: Introduce sub-classes for path-sensitive and basic reports.
Checkers are now required to specify whether they're creating a
path-sensitive report or a path-insensitive report by constructing an
object of the respective type.

This makes BugReporter more independent from the rest of the Static Analyzer
because all Analyzer-specific code is now in sub-classes.

Jonas Devlieghere 2b3d49b610 [Clang] Migrate llvm::make_unique to std::make_unique

implementation from STLExtras.h. This patch is a mechanical replacement

Kristof Umann fc76d8551f [analyzer][NFC] Refactoring BugReporter.cpp P4.: If it can be const, make it const
When I'm new to a file/codebase, I personally find C++'s strong static type
system to be a great aid. BugReporter.cpp is still painful to read however:
function calls are made with mile long parameter lists, seemingly all of them
taken with a non-const reference/pointer. This patch fixes nothing but this:
make a few things const, and hammer it until it compiles.

Chandler Carruth 2946cd7010 Update the file headers across all of the LLVM projects in the monorepo
to reflect the new license.

We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.

Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

The complicated machinery for passing the summary log around is actually
only used for one thing! To figure out whether the "dealloc" message was

Since I have tried to extend it for other uses and failed (it's actually
very hard to use), I think it's much better to simply use a tag and
remove the summary log altogether.
