David Majnemer 8c79db1741 [CodeView] Take the StreamRef::readBytes offset into account when validating
We only considered the length of the operation and the length of the
StreamRef without considered what it meant for the offset to be at a
non-zero position.

Use the type index of the underlying type unless we have a typedef from

Dan Liew fba4a67a32 [LibFuzzer] Disable compiling and running the LibFuzzer dataflow sanitizer tests on Apple platforms.
This fixes a broken part of the build on OSX as the dataflow sanitizer is not supported
on OSX yet.

Dan Liew d3c33116fd [LibFuzzer] Reimplement how the optional user functions are called.
The motivation for this change is to fix linking issues on OSX.
However this only partially fixes linking issues (the uninstrumented
tests and a few others  won't succesfully link yet).

This change introduces a struct of function pointers
(``fuzzer::ExternalFuntions``) which when initialised will point to the
optional functions if they are available.  Currently these
``LLVMFuzzerInitialize`` and ``LLVMFuzzerCustomMutator`` functions.

Two implementations of ``fuzzer::ExternalFunctions`` constructor are
provided one for Linux and one for OSX.

The OSX implementation uses ``dlsym()`` because the prior implementation
using weak symbols does not work unless the additional flags are passed
to the linker.

The Linux implementation continues to use weak symbols because the
``dlsym()`` approach does not work unless additional flags are passed
to the linker.

Craig Topper ca9c0801e1 [X86] Add AVX 256-bit load and stores to fast isel.
I'm not sure why this was missing for so long.

This also exposed that we were picking floating point 256-bit VMOVNTPS for some integer types in normal isel for AVX1 even though VMOVNTDQ is available. In practice it doesn't matter due to the execution dependency fix pass, but it required extra isel patterns. Fixing that in a follow up commit.

Eric Fiselier ffd1893df5 [libcxxabi] Allow target flags to affect configuration tests.
Summary:
This patch changes the libc++abi CMake so that it adds certain target flags like  '-m32' or '--gcc-toolchain' before including `config-ix.cmake`.
Since these flags can affect things like `check_library_exists([...])` they needed to be added before the tests are performed.

Additionally this patch adds `LIBCXXABI_BUILD_32_BITS` which defaults to `LLVM_BUILD_32_BITS`.

Summary:
This patch adds a "REQUIRES-ANY" feature test that is disjunctive. This marks a test as `UNSUPPORTED` if none of the specified features are available.

Libc++ has the need to write feature test such as `// REQUIRES-ANY: c++98, c++03`  when testing of behavior that is specific to older dialects but has since changed.
