Summary:
Added option -gline-directives-only to support emission of the debug directives
only. It behaves very similar to -gline-tables-only, except that it sets
llvm debug info emission kind to
llvm::DICompileUnit::DebugDirectivesOnly.

There are two types of dynamic initializer stubs. There's
`dynamic initializer for 'x''(void)
and
`dynamic initializer for `static Foo::Bar StaticDataMember''(void)
The second case is disambiguated from the first by the presence of
a ? after the operator code. So the first will appear something like
?__E<name> while the second will appear something like ?__E?<name>.
clang-cl was mangling these both the same though. This patch
matches behavior with cl.

Summary:
Instead of listing all the spellings (including attribute namespaces) in
the section heading, only list the actual attribute names there, and
list the spellings in the supported syntaxes table.
This allows us to properly describe things like [[fallthrough]], for
which we allow a clang:: prefix in C++ but not in C, and AlwaysInline,
which has one spelling as a GNU attribute and a different spelling as a
keyword, without needing to repeat the syntax description in the
documentation text.

Return value of dyn_cast_or_null should be checked before use.
Otherwise we may put a null pointer into the map as a key and eventually

Summary:
Port libFuzzer to windows-msvc.
This patch allows libFuzzer targets to be built and run on Windows, using -fsanitize=fuzzer and/or fsanitize=fuzzer-no-link. It allows these forms of coverage instrumentation to work on Windows as well.
It does not fix all issues, such as those with -fsanitize-coverage=stack-depth, which is not usable on Windows as of this patch.
It also does not fix any libFuzzer integration tests. Nearly all of them fail to compile, fixing them will come in a later patch, so libFuzzer tests are disabled on Windows until them.

Object linking isn't supported, so it's not useful
to emit default visibility. Default visibility requires
relocations we don't yet support for functions compiled
in another translation unit.
WebAssembly already does this, although they insert these
arguments in a different place for some reason.

ASTContext::applyObjCProtocolQualifiers will return a canonical type when given
a canonical type and an array of canonical protocols. If the protocols are not
canonical then the returned type is also not canonical. Since a canonical type is needed, canonicalize the returned type before using it. This later prevents
a type from having a non-canonical canonical type.

how we parse source code.
Instead of implicitly opting all undocumented attributes out of '#pragma
clang attribute' support, explicitly opt them all out and remove the
documentation check from TableGen.
(No new attributes should be added without documentation, so this has
little chance of backsliding. We already support the pragma on one
undocumented attribute, so we don't even want to enforce our old
"rule".)
No functionality change intended.
llvm-svn: 341009
Introduce a new MemRegion sub-class, CXXDerivedObjectRegion, which is
the opposite of CXXBaseObjectRegion, to represent such casts. Such region is
a bit weird because it is by design bigger than its super-region.
But it's not harmful when it is put on top of a SymbolicRegion
that has unknown extent anyway.
Offset computation for CXXDerivedObjectRegion and proper modeling of casts
still remains to be implemented.
