- Fix the bug with transition handling in ExprInspectionChecker's
checkDeadSymbols implementation.
- Test this bug by adding a new function clang_analyzer_numTimesReached() to
catch number of passes through the code, which should be handy for testing
against unintended state splits.
- Add two more functions should help debugging issues quickly without running
the debugger or dumping exploded graphs - clang_analyzer_dump() which dump()s
an SVal argument to a warning message, and clang_analyzer_printState(), which
dump()s the current program state to stderr.

Other AST consumers can deserialize interesting decls that we might
codegen, but they won't make it to the final object file and can trigger
assertions in debug information generation after finalization.

Otherwise MSVC and clang-cl will see "extern inline" after merging
redeclarations and emit it in all TUs that include Type.h and Decl.h.
Noticed by inspection, since it's always the first thing to get emitted.

Avoid using shortcut for const qualified non-constant address space
aggregate variables while generating them on the stack such that
the alloca object is used instead of a global variable containing
initializer.

Defining DEBUG_TYPE in a header file doesn't make sense.

Specifically, if the RHS of a comma is a complex binary expression and
spans multiple lines, insert a line break before it. This usually is
often more readable compared to producing a hanging indent. See changes
in FormatTest.cpp for examples.

On Windows, Clang is mangling lambdas in default member initializers
incorrectly. See PR31197.
This is causing redness on the self-host bots. Work around the problem
locally so we aren't blind to further issues.

Add a set of unit tests for the distro detection code. The tests use an
in-memory virtual filesystems resembling release files for various
distributions supported. All release files are provided (not only the
ones directly used) in order to guarantee that one of the rules will not
mistakenly recognize the distribution incorrectly due to the additional
files (e.g. Ubuntu as Debian).

Fix recognizing newer OpenSUSE versions that combine the two version

Refactor the Distro enum along with helper functions into a full-fledged
Distro class, inspired by llvm::Triple, and make it a public API.
The new class wraps the enum with necessary comparison operators, adding
the convenience Is*() methods and a constructor performing
the detection. The public API is needed to run the unit tests (D25869).

This solves PR23715 in a way that is compatible with LTO.
MSVC supports jumping to source-level labels and between inline asm
blocks, but we don't.
Also revert the old solution, r255201, which was to mark these calls as
noduplicate.

If member expression is used in the task region and the base expression
is a DeclRefExp and the variable used in this ref expression is private,
it should be marked as implicitly firstprivate inside this region. Patch

Summary:
clang-tidy checks frequently use source ranges of functions.
The source range of constructors and destructors in template instantiations
is currently a single token.
The factory method for constructors and destructors does not allow the
end source location to be specified.
Set end location manually after creating instantiation.

Since r274049, for an inheriting constructor declaration, the name of the using
declaration (and using shadow declaration comes from the using declaration) is
the name of a derived class, not the base class (line 8225-8232 of
lib/Sema/SemaDeclCXX.cpp in https://reviews.llvm.org/rL274049). Because of
this, name-based lookup performed inside Sema::LookupConstructors returns not
only CXXConstructorDecls but also Using(Shadow)Decls, which results assertion
failure reported in PR29087.

Documentation for some of the avxintrin.h's intrinsics errorneously said that
non VEX-prefixed instructions could be generated. This was fixed.

Summary:
If the `FromDecl` is a class forward declaration, the reference is
still considered as referring to the original definition given the nature
of forward-declarations, so we can't do a raw name replacement in this case.

Summary:
For example, this case was missed when looking for different but canonical
namespaces. UseContext in this case should be considered as in the canonical
namespace.
```
namespace a { namespace b { <FromContext> } }
namespace a { namespace b { namespace c { <UseContext> } } }
```

(commit again after fixing the buildbot failures)
This adds various overloads of the following builtins to altivec.h:
vec_neg
vec_nabs
vec_adde
vec_addec
vec_sube
vec_subec
vec_subc
Note that for vec_sub builtins on 32 bit integers, the semantics is similar to
what ISA describes for instructions like vsubecuq that work on quadwords: the
first operand is added to the one's complement of the second operand. (As
opposed to two's complement which I expected).
