This includes special members (copy/default ctor, copy assign, default
ctor) and template specializations for member function templates.
Good for a 5% decrease (1.80 to 1.71 GB) in size on Clang+LLVM's .dwo
files (when using fission).

Make sure we can properly generate code when the UUID has curly braces
on it, strip the curly braces at the sema layer.
This fixes PR16813.

Summary:
ExprEngine had code which specificaly disabled using CXXTempObjectRegions in
InitListExprs. This was a hack put in r168757 to silence a false positive.
The underlying problem seems to have been fixed in the mean time, as removing
this code doesn't seem to break anything. Therefore I propose to remove it and
solve PR16629 in the process.

We mangled them like:
L___uuid_12345678-1234-1234-1234-123456789abc
We should've mangled them like:
__GUID_12345678_1234_1234_1234_123456789abc
Furthermore, they are external symbols.

of local classes. We were previously handling this by performing qualified
lookup within a function declaration(!!); replace it with the proper scope
lookup.

This option prints information about #included files to stderr. Clang could
already do it, this patch just teaches the existing code about the /showIncludes
style and adds the flag.

We were exposing the extra alignment given to large arrays. The new behavior
matches gcc, which is a good thing since this is a gcc extension.
Thanks to Joerg Sonnenberger for noticing it.
While at it, centralize the method description in the .h file.

This reverts commit r187991 and adjusts the comment. /Za is much more
involved, and we don't want to give anyone the impression we actually
support it.

'-fno-unroll-loops'. The option to the backend is even called
'DisableUnrollLoops'. This is precisely the form that Clang *didn't*
support. We didn't recognize the flag, we didn't pass it to the CC1
layer, and even if we did we wouldn't use it. Clang only inspected the
positive form of the flag, and only did so to enable loop unrolling when
the optimization level wasn't high enough. This only occurs for an
optimization level that even has a chance of running the loop unroller
when optimizing for size.
This commit wires up the 'no' variant, and switches the code to actually
follow the standard flag pattern of using the last flag and allowing
a flag in either direction to override the default.
I think this is still wrong. I don't know why we disable the loop
unroller entirely *from Clang* when optimizing for size, as the loop
unrolling pass *already has special logic* for the case where the
function is attributed as optimized for size! We should really be
trusting that. Maybe in a follow-up patch, I don't really want to change
behavior here.

Summary:
UBSan was checking for alignment of the derived class on the pointer to
the base class, before converting. With some class hierarchies, this could
generate false positives.
Added test-case.

These flags set some preprocessor macros and injects a dependency
on the runtime library into the object file, which later is picked up
by the linker.
This also adds a new CC1 flag for adding a dependent library.

DataFlowSanitizer is a generalised dynamic data flow analysis.
Unlike other Sanitizer tools, this tool is not designed to detect a
specific class of bugs on its own. Instead, it provides a generic
dynamic data flow analysis framework to be used by clients to help
detect application-specific issues within their own code.

The problem was that an enum without closing semicolon could be associated as a forward enum
in an erroneous declaration, leading to the identifier being associated with the enum decl but
without a declaration actually referencing it.
This resulted in not having it serialized before serializing the identifier that is associated with.
Also prevent the ASTUnit from querying the serialized DeclID for an invalid top-level decl; it may not
have been serialized.

In particular, left braces after an enum declaration now occur on their
own line. Further, when short ifs/whiles are allowed these no longer
cause the left brace to be on the same line as the if/while when a
brace is included.
