The complete dtor is only emitted when there is a virtual destructor. The test
itself was incorrect, so the issue in the code was not noticed.

Teach DeduceFromInitializerList in SemaTemplateDeduction.cpp to deduce against array (constant and dependent sized) parameters (really, reference to arrays since they don't decay to pointers), by checking if the template parameter is either one of those kinds of arrays, and if so, deducing each initializer list element against the element type, and then deducing the array bound if needed.
In brief, this patch enables the following code:
template<class T, int N> int *f(T (&&)[N]);
int *ip = f({1, 2, 3});

r251874 reworked the way we handle properties declared within
Objective-C class extensions, which had the effective of tightening up
property checking in a number of places. In this particular class of
cases, we end up complaining about "atomic" mismatches between an
implicitly-atomic, readonly property and a nonatomic, readwrite
property, which doesn't make sense because "atomic" is essentially
irrelevant to readonly properties.
Therefore, suppress this diagnostic when the readonly property is
implicitly atomic. Fixes rdar://problem/23803109.

The code used "isa" to check the type and then "getAs" to look through
sugar; we need to look through the sugar when checking, too, otherwise
any kind of sugar (nullability qualifiers in the example; or a
typedef) will thwart this semantic check. Fixes rdar://problem/23804250.

Currently, we emit warnings in some cases where nonnull function
parameters are compared against null. This patch extends this support
to warn when comparing the result of `returns_nonnull` functions
against null.
More specifically, we will now warn cases like:
int *foo() __attribute__((returns_nonnull));
int main() {
if (foo() == NULL) {} // warning: will always evaluate to false
}

When attempting to map a source into a given level of macro expansion,
this code was ignoring the possibility that the start and end of the
range might take wildly different paths through the tree of macro
expansions. It was assuming that the begin spelling location would
always precede the end spelling location, which is false. A macro can
easily transpose its arguments.
This also fixes a related issue where there are extra macro arguments
between the begin location and the end location. In this situation, we
now highlight the entire macro invocation.
Pair programmed with Richard Smith.
Fixes PR12818.

When a C++ lambda captures a variable-length array, it creates a capture
field to store the size of the array. The initialization expression for this
capture is null, which led the analyzer to crash when initializing the field.
To avoid this, use the size expression from the VLA type to determine the
initialization value.

Hopefully fix the remaining bot failure from r254927. Remove
target specification since it shouldn't be needed, and this causes
an error when trying to check the pass execution structure in
test/CodeGen/thinlto_backend.c on non-x86 arches.

If we're initializing a TypeLoc from one that's been allocated with
different alignment, memcpy will get the padding wrong. The `copy`
method already checks and handles this case, so we should just defer
to it.
This also drops the `const` off of the `initializeFullCopy`
declarations, since it isn't even remotely true (and the compiler
notices when we try to call copy() instead of tricking it with
memcpy).
Fixes llvm.org/pr23516.

Summary:
Adds new option -fthinlto-index=<file> to invoke the LTO pipeline
along with function importing via clang using the supplied function
summary index file. This supports invoking the parallel ThinLTO
backend processes in a distributed build environment via clang.
Additionally, this causes the module linker to be invoked on the bitcode
file being compiled to perform any necessary promotion and renaming of
locals that are exported via the function summary index file.
Add a couple tests that confirm we get expected errors when we try to
use the new option on a file that isn't bitcode, or specify an invalid
index file. The tests also confirm that we trigger the expected function
import pass.

Unfortunately, clang currently checks for a certain brokenness of implementations of std::initializer_list in CodeGen (void
AggExprEmitter::VisitCXXStdInitializerListExpr), not in SemaInit. Until that is fixed, make sure we don't let broken attempts that are aggregates leak through into sema, which allows maintenance of expected invariants, and avoids triggering an assertion.
