I think "i128", that I conditioned out, could be completely removed.
MS Compiler doesn't accept i128. We can assume no one would use i128.

performed, to determine whether that special member is deleted or constexpr.
That overload resolution process can in turn trigger the instantiation of a
template, which can do anything, including triggering the declaration of that
very same special member function. When this happens, do not try to recursively
declare the special member -- that's impossible. Instead, only try to realise
the truth. There is no special member.

in deciding a copy/dispose field is needed in a byref structure
and when generating the copy/dispose helpers. In certain
cases, these fields were being added but no copy/dispose was
being generated. This was uncovered in ARC, but not in MRR.

the original parameter or return type.
Since we do not accurately represent the data fields of a union, we should not
directly load or store a union type.
As an exmple, if we have i8,i8, i32, i32 as one field type and i32,i32 as
another field type, the first field type will be chosen to represent the union.
If we load with the union's type, the 3rd byte and the 4th byte will be skipped.

determine which member function would be the callee from within the template
definition, don't pass that function as a "non-member function" to
CreateOverloadedBinOp. Instead, just rely on it to select the member function
for itself.

string literal needs cleaning (because it contains line-splicing in the
encoding prefix or in the ud-suffix), do not clean the section between the
double-quotes -- that's the "raw" bit!

constructor/assignment operator with a const-qualified parameter type. The
prior method for determining this incorrectly used overload resolution.

allocated using the allocator associated with an ASTContext.
Use this inside CXXRecordDecl::DefinitionData instead of an UnresolvedSet to
avoid a potential memory leak.

a special member" diagnostic from warning to error, and fix the cases where it
produced diagnostics with incorrect wording.
We don't support this as an extension, and we ban it even in C++98 mode. This
breaks too much (for instance, the ABI-specified calling convention for a type
can change if it acquires a copy constructor through the addition of a default
argument).

The stop-gap here is to just drop such objects when processing the InitListExpr.
We still need a better solution.
Fixes <rdar://problem/12755044>.

This was also covered by <rdar://problem/12753384>. The static analyzer
evaluates a CXXConstructExpr within an initializer expression and
RegionStore doesn't know how to handle the resulting CXXTempObjectRegion
that gets created. We need a better solution than just dropping the
value, but we need to better understand how to implement the right
semantics here.
Thanks to Jordan for his help diagnosing the behavior here.

objc_loadWeak. This retains and autorelease the weakly-refereced
object. This hidden autorelease sometimes makes __weak variable alive even
after the weak reference is erased, because the object is still referenced
by an autorelease pool. This patch overcomes this behavior by loading a
weak object via call to objc_loadWeakRetained(), followng it by objc_release
at appropriate place, thereby removing the hidden autorelease. // rdar://10849570

r128056 moved PrettyStackTraceParserEntry construction from Parser.h
to ParseAST.cpp, so there's no need to keep this class in a header.

ELF ABI.
Complex values are to be passed in registers as though the real and
imaginary parts were passed as separate parameters. Prior to this
patch, complex values were passed as byval aggregates. It turns out
that specifying getDirect() for all complex types when classifying the
argument type results in the desired behavior.
The new Clang test case verifies that the correct LLVM IR is generated
for caller and callee for each of the underlying types for _Complex.
