Johannes Doerfert d36553753e Simplify the type adjustment in the IslExprBuilder
We now have a simple function to adjust/unify the types of two (or three)
  operands before an operation that requieres the same type for all operands.
  Due to this change we will not promote parameters that are added to i64
  anymore if that is not needed.

Simon Pilgrim 0afd5a4d80 [X86][SSE] Replace (V)CVTTPS2DQ and VCVTTPD2DQ truncating (round to zero) f32/f64 to i32 with generic IR (llvm)
This patch removes the llvm intrinsics (V)CVTTPS2DQ and VCVTTPD2DQ truncation (round to zero) conversions and auto-upgrades to FP_TO_SINT calls instead.

Note: I looked at updating CVTTPD2DQ as well but this still requires a lot more work to correctly lower.

Chandler Carruth 7ae684a8b4 Switch statistics to use relaxed updates to a std::atomic.
This removes usage of the hacky, incorrect, and TSan-unfriendly
home-grown atomics. It should actually be more efficient in some cases.

Based on our existing usage of <atomic>, all of this is portably
available AFAICT. One small challenge is initializing the stastic, but
I've tried a comparable sample out on MSVC (the most likely to complain
here) and it seems to work. Will have to watch the build bots of course.

Chandler Carruth a30f684a67 [ADT] Remove unused multiply and divide operator overloads on
statistics.

Scaling statistics atomically doesn't make any sense anyways, and none
were using these. If you find yourself wanting to do this, you should
probably keep a local count that you scale and then apply that after
scaling to the shared statistic object.

Eric Fiselier 2d6714a9c5 Partially revert r270816: build with -fvisibility=hidden.
This patch breaks the ABI on linux when libc++abi.a is statically linked into
libc++.so. Certain libc++ symbols get exported from libc++abi.a as hidden
and therefore they also get hidden in libc++.so.

The symbols is question are:

* _ZNKSt3__121__basic_string_commonILb1EE20__throw_out_of_rangeEv
* _ZNKSt3__121__basic_string_commonILb1EE20__throw_length_errorEv
* _ZNKSt3__120__vector_base_commonILb1EE20__throw_length_errorEv

I imagine we just need to fix the visibility for these symbols in the libc++
headers but I'm reverting the patch until it's sorted.

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.
