5183147e2d wire timeouts and exceptional inferior process exits through the test event system
The results formatter system is now fed timeouts and exceptional process
exits (i.e. inferior dotest.py process that exited by signal on POSIX
systems).

If a timeout or exceptional exit happens while a test method is running
on the worker queue, the timeout or exceptional exit is charged and
reported against that test method.  Otherwise, if no test method was
running at the time of the timeout or exceptional exit, only the test
filename will be reported as the TIMEOUT or ERROR.

12f7929177 Add some additional safety checks to the StructuredData access
methods - lldb can still crash pretty easily on corrupt JSON text,
and these will help eliminate a bunch of cases where that would
result in a crash.  Some of the methods would check that e.g.
GetItemAtIndex would actually return an item before dereferencing it,
some would not, that kind of thing.

b5104b5884 Fix the order of destructors in LibLTOCodeGenerator
Summary:
The order of destructors in LTOCodeGenerator gets changed in r254696.
It is possible for LTOCodeGenerator to have a MergedModule created in
the OwnedContext, in which case the module must be destructed before
the context.

97564c3a1b [AArch64][ARM] Don't base interleaved op legality on type alloc size.
Otherwise, we think that most types that look like they'd fit in a
legal vector type are legal (so, basically, *any* vector type with a
size between 33 and 128 bits, I think, since we use pow2 alignment;
e.g., v2i25, v3f32, ...).

DataLayout::getTypeAllocSize rounds up based on alignment.
When checking for target intrinsic legality, that's not what we want:
if rounding makes a difference, the type isn't legal, and the
target intrinsics shouldn't be used, as they are always assumed legal.

One could make the argument that alloc size is ultimately the most
relevant here, since we're dealing with LD/ST intrinsics. That's only
true if we did legalize them though; that's a problem for another day.

Use DataLayout::getTypeSizeInBits instead of getTypeAllocSizeInBits.
Type::getSizeInBits can't be used because that'd gratuitously break
pointer vector support.

Some of these uses are currently fine, because we only hit them when
the type is already known legal (e.g., r114454). Update them for
consistency. It's faster to avoid the rounding anyway!

466d4b006b Don't bypass the GOT for delta32toGOT references.
The gcc_except_tab was generating these references to point to the typeinfo in the data section.

gcc_except_tab also had the DW_EH_PE_indirect flag set which means that at runtime we are going
to dereference this entry as if it is in the GOT.

any kind of sugar (nullability qualifiers in the example; or a

323e00d9c7 [X86][AVX] Fold loads + splats into broadcast instructions
On AVX and AVX2, BROADCAST instructions can load a scalar into all elements of a target vector.

This patch improves the lowering of 'splat' shuffles of a loaded vector into a broadcast - currently the lowering only works for cases where we are splatting the zero'th element, which is now generalised to any element.

6b63d576c3 [PPC64, TSAN] Provide setjmp interceptor support for PPC64
This patch provides the assembly support for setjmp/longjmp for use
with the thread sanitizer.  This is a big more complicated than for
aarch64, because sibcalls are only legal under our ABIs if the TOC
pointer is unchanged.  Since the true setjmp function trashes the TOC
pointer, and we have to leave the stack in a correct state, we emulate
the setjmp function rather than branching to it.

We also need to materialize the TOC for cases where the _setjmp code
is called from libc.  This is done differently under the ELFv1 and
ELFv2 ABIs.

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
}

2979162732 [PPC64, TSAN] LLVM basic enablement of thread sanitizer for PPC64 (BE and LE)
This patch is by Simone Atzeni with portions by Adhemerval Zanella.

This contains the LLVM patches to enable the thread sanitizer for
PPC64, both big- and little-endian.  Two different virtual memory
sizes are supported:  Old kernels use a 44-bit address space, while
newer kernels require a 46-bit address space.

There are two companion patches that will be added shortly.  There is
a Clang patch to actually turn on the use of the thread sanitizer for
PPC64.  There is also a patch that I wrote to provide interceptor
support for setjmp/longjmp on PPC64.

8fc2cbf933 [EarlyCSE] Value forwarding for unordered atomics
This patch teaches the fully redundant load part of EarlyCSE how to forward from atomic and volatile loads and stores, and how to eliminate unordered atomics (only). This patch does not include dead store elimination support for unordered atomics, that will follow in the near future.

The basic idea is that we allow all loads and stores to be tracked by the AvailableLoad table. We store a bit in the table which tracks whether load/store was atomic, and then only replace atomic loads with ones which were also atomic.

No attempt is made to refine our handling of ordered loads or stores. Those are still treated as full fences. We could pretty easily extend the release fence handling to release stores, but that should be a separate patch.
