ARM: don't rely on push/pop reglists being in order when folding SP adjust.
It would be a very nice invariant to rely on, but unfortunately it doesn't
necessarily hold (and the causes of mis-sorted reglists appear to be quite
varied) so to be robust the frame lowering code can't assume that the first
register in the list is also the first one that actually gets pushed.

push {r8, r4, r7, lr}

This reapplies revision 285093. Original commit message:
The branch folding pass tail merges blocks into a common-tail. However, the
tail retains the debug information from one of the original inputs to the
merge (chosen randomly). This is a problem for sampled-based PGO, as hits
on the common-tail will be attributed to whichever block was chosen,
irrespective of which path was actually taken to the common-tail.

[scudo] Lay the foundation for 32-bit support
Summary:
In order to support 32-bit platforms, we have to make some adjustments in
multiple locations, one of them being the Scudo chunk header. For it to fit on
64 bits (as a reminder, on x64 it's 128 bits), I had to crunch the space taken
by some of the fields. In order to keep the offset field small, the secondary
allocator was changed to accomodate aligned allocations for larger alignments,
hence making the offset constant for chunks serviced by it.
The resulting header candidate has been added, and further modifications to
allow 32-bit support will follow.
Another notable change is the addition of MaybeStartBackgroudThread() to allow
release of the memory to the OS.

Current generation of lifetime intrinsics does not handle cases like:
```
{
char x;

We will get code like this:
```
%x = alloca i8, align 1

br label %l1
l1:
%call = call i32 @bar(i8* nonnull %x, i32 1)
call void @llvm.lifetime.end(i64 1, i8* nonnull %x)
br label %l1
```
So the second time bar was called for x which is marked as dead.
Lifetime markers here are misleading so it's better to remove them at all.

clang (2329 targets).

[AVX-512] Add scalar vfmsub/vfnmsub mask3 intrinsics
Summary: Clang's intrinsic header currently tries to negate the third operand of a vfmadd mask3 in order to create vfmsub, but this fails isel. This patch adds scalar vfmsub and vfnmsub mask3 that we can use instead to avoid the negate. This is consistent with the packed instructions.

Treat module headers wrapped by our builtin headers as implicitly being textual
headers. We previously got this check backwards and treated the wrapper header
as being textual.
This is important because our wrapper headers sometimes inject macros into the
system headers that they #include_next, and sometimes replace them entirely.

Implement name mangling proposal for exception specifications from cxx-abi-dev 2016-10-11.
This has the following ABI impact:
1) Functions whose parameter or return types are non-throwing function pointer
types have different manglings in c++1z mode from prior modes. This is
necessary because c++1z permits overloading on the noexceptness of function
pointer parameter types. A warning is issued for cases that will change
manglings in c++1z mode.
2) Functions whose parameter or return types contain instantiation-dependent
exception specifications change manglings in all modes. This is necessary
to support overloading on / SFINAE in these exception specifications, which
a careful reading of the standard indicates has essentially always been
permitted.
Note that, in order to be affected by these changes, the code in question must
specify an exception specification on a function pointer/reference type that is
written syntactically within the declaration of another function. Such
declarations are very rare, and I have so far been unable to find any code
that would be affected by this. (Note that such things will probably become
more common in C++17, since it's a lot easier to get a noexcept function type
as a function parameter / return type there.)
This change does not affect the set of symbols produced by a build of clang,
libc++, or libc++abi.

Read section headers upfront.
Instead of storing a pointer, store the members we need.
The reason for doing this is that it makes it far easier to create
synthetic sections. It also avoids reading data from files multiple
times., which might help with cross endian linking and host
architectures with slow unaligned access.
There are obvious compacting opportunities, but this already has mixed
results even on native x86_64 linking.
There is also the possibility of better refactoring the code for
handling common symbols, but this already shows that a custom class is
not necessary.
