This allows using a different standard library (the one from argv[0] in
the compilation database) with the correct builtins.

xmmintrin.h a bit more directed. If for whatever reason modules are enabled but
we textually include one of these headers, don't deploy the special case for

interface is declared in a module.
The private @implementation of an @interface may have additional
hidden ivars so we should not defer to the public version of the
type that is found in the module.

Summary:
This is a follow-on to apply Duncan's new DIType ODR uniquing from
r266549 and r266713 in more places.
When invoking ThinLTO backend compiles via clang (for a distributed
build), invoke enableDebugTypeODRUniquing() before parsing the module.

A subsequent patch will propose a "distribute" loop hint. Similarly to
unroll, this does not have a "assume_safety" argument either so this
condition will get more complex.

The intrinsic is now called llvm.thread.pointer, not
llvm.aarch64.thread.pointer. Also, the code handling it in CGBuiltin.cpp
is dead - it's already covered by GCCBuiltin. Remove it.

r259537 added vfma/vfms to armv7, but the builtin was only lowered
on the AArch64 side. Instead of supporting it on ARM, get rid of it.
The vfms builtin lowered to:
%nb = fsub float -0.0, %b
%r = @llvm.fma.f32(%a, %nb, %c)
Instead, define the operation in terms of vfma, and swap the
multiplicands. It now lowers to:
%na = fsub float -0.0, %a
%r = @llvm.fma.f32(%na, %b, %c)
This matches the instruction more closely, and lets current LLVM
generate the "natural" operand ordering:
fmls.2s v0, v1, v2
instead of the crooked (but equivalent):
fmls.2s v0, v2, v1
Except for theses changes, assembly is identical.
LLVM accepts both commutations, and the LLVM tests in:
test/CodeGen/AArch64/arm64-fmadd.ll
test/CodeGen/AArch64/fp-dp3.ll
test/CodeGen/AArch64/neon-fma.ll
test/CodeGen/ARM/fusedMAC.ll
already check either the new one only, or both.
Also verified against the test-suite unittests.

Currently, for the ppc64--gnu and aarch64 ABIs, we recognize:
typedef __attribute__((__ext_vector_type__(3))) float v3f32;
typedef __attribute__((__ext_vector_type__(16))) char v16i8;
struct HFA {
v3f32 a;
v16i8 b;
};
as an HFA. Since the first type encountered is used as the base type,
we pass the HFA as:
[2 x <3 x float>]
Which leads to incorrect IR (relying on padding values) when the
second field is used.
Instead, explicitly widen the vector (after size rounding) in
isHomogeneousAggregate.

Prevent hasAncestor from comparing nodes that are not supported.
hasDescendant was fixed some time ago to avoid this problem.
I'm applying the same fix to hasAncestor: if any object in the Builder map is
not comparable, skip the cache.

Summary:
Change `import` and `export` parsing to special case the renaming
syntax (`import x, {y as bar} ...`, `export {x}`) and otherwise just
parse a regular structural element.
This simplifies the code a bit and should be more correct - it's easier
to recognise the specific import syntax than to recognise arbitrary
expressions and declarations.

With this patch compiler emits warning if it tries to make implicit instantiation
of a template but cannot find the template definition. The warning can be suppressed
by explicit instantiation declaration or by command line options
-Wundefined-var-template and -Wundefined-func-template. The implementation follows
