clang-format: Improve formatting of builder-type calls.

This removes a formatting choice that was added at one point, but is
not generally liked by users. Specifically, in builder-type calls, do
(easily) break if the object before the ./-> is either a field or a
parameter-less function call. I.e., don't break after "aa.aa.aa" or
"aa.aa.aa()". In general, these sequences in builder-type calls are
seen as a single entity and thus breaking them up is a bad idea.

Eliminate CXXConstructorDecl::IsImplicitlyDefined.

This field is just IsDefaulted && !IsDeleted; in all places it's used,
a simple check for isDefaulted() is superior anyway, and we were forgetting
to set it in a few cases.

Also eliminate CXXDestructorDecl::IsImplicitlyDefined, for the same reasons.

No intended functionality change.

Correctly allign arrays on 32 bit systems.

Before this patch we would align

long long int big[1024];

to 4 bytes on 32 bit systems. The problem is that we were only looking
at the element type when getLargeArrayMinWidth returned non zero.

Fixes a couple of bugs with the Allman brace breaking.

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.

Patch by Thomas Gibson-Robinson.

[PCH] Fix a PCH serialization crash, with invalid code related to forward enum references.

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.

DataFlowSanitizer; Clang changes.

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.

clang-cl: Support the run-time selection options (/MD, /MT et al.)

These flags set some preprocessor macros and injects a dependency

by the linker.

This also adds a new CC1 flag for adding a dependent library.

UBSan: Fix alignment checks emitted in downcasts.

Summary:
UBSan was checking for alignment of the derived class on the pointer to
