Add MCContext argument to MCAsmBackend::applyFixup for error reporting
A number of backends (AArch64, MIPS, ARM) have been using
MCContext::reportError to report issues such as out-of-range fixup values in
their TgtAsmBackend. This is great, but because MCContext couldn't easily be
threaded through to the adjustFixupValue helper function from its usual
callsite (applyFixup), these backends ended up adding an MCContext* argument

[X86] Relax assert in broadcast-of-subvector lowering.
Before r294774, there was a problem when lowering broadcasts to use
128-bit subvectors.
When we looked through a bitcast to find the broadcast input, we'd keep
using the original type, so you'd end up with things like:
(v8f32 (broadcast
(v4f32 (extract_subvector
(v8i32 V),
...))
))
r294774 fixed it to always emit subvectors with the scalar type of the
original source.
It also introduced some asserts, to check that we use scalars with
the same size, and vectors with the same number of elements.
The scalar size equality is checked earlier when looking through bitcasts,
and is a useful assert.
However, the number of elements don't have to be identical: we're always
going to extract a 128-bit subvector, and we can have different size
inputs if we looked through a concat_vector to find a 256-bit source.
Relax the overzealous assert.
Replace it with a check of the original source vector being 256 or 512
bits. If it's 128 bits, we can't extract_subvector from it.

The pragma has the same block scope rules as STDC FP_CONTRACT, i.e. it can be

Similarly to STDC FP_CONTRACT there is no need to use attributes. First an
annotate token is inserted with the parsed details of the pragma. Then the
annotate token is parsed in the proper contexts and the Sema is updated with
the corresponding FPOptions using the shared ActOn function with STDC
FP_CONTRACT.
After this the FPOptions from the Sema is propagated into the AST expression
nodes. There is no change here.
I was going to add a 'default' option besides 'on/off/fast' similar to STDC

Don't resolve hidden undef to a DSO.
The ELF spec says:
all of the non-default visibility attributes, when applied to a symbol
reference, imply that a definition to satisfy that reference must be
provided within the current executable or shared object.
But we were trying to resolve those undef references to shared
symbols. That causes odd results like creating a got entry with
a relocation pointing to 0.

Implement host CPU detection for AArch64
This shares detection logic with ARM(32), since AArch64 capable CPUs may
also run in 32-bit system mode.
We observe weird /proc/cpuinfo output for MSM8992 and MSM8994, where
they report all CPU cores as one single model, depending on which CPU
core the kernel is running on. As a workaround, we hardcode the known
CPU part name for these SoCs.
For big.LITTLE systems, this patch would only return the part name of
the first core (usually the little core). Proper support will be added
in a follow-up change.

[RuntimeDyld] Make RuntimeDyld honor the ProcessAllSections flag.
When the ProcessAllSections flag (introduced in r204398) is set RuntimeDyld is
supposed to make a call to the client's memory manager for every section in each
object that is loaded. Due to some missing checks, this was not happening in all
cases. This patch adds the missing cases, and fixes the Orc unit test that
verifies correct behavior for ProcessAllSections (The unit test had been
silently bailing out due to an ordering issue: a change in the test order meant
that this unit-test was running before the native target was registered. This
issue has also been fixed in this patch).

Fixed the assertion due to absence of source location for

During Sema checks the source location is being expected

The change is not specific to OpenCL. But it is particularly
common for OpenCL types to be declared implicitly in Clang
to support the mode without the standard header.

Fix exception address alignment test for EHABI
This test fails on ARM bare-metal targets because it assumes the Itanium ABI,
whereas EHABI requires the exception address to be 8-byte aligned.
I was a bit puzzled at first because this should've failed on the public
arm-linux builder too. I think the reason it passes there is because we don't
include libunwind headers in the include path when running the libcxxabi tests,
so the system unwind.h gets picked up.
