Visual Studio 2013 and up have these functions, and we don't need to
support older versions.

There are some remaining _LIBCPP_MSVCRT exclusions which are present on
Visual Studio 2015 but not 2013. Those will be addressed in a follow-up.

asan_device_setup script is using LD_PRELOAD to inject the ASan
runtime library into the Zygote process. This breaks when the Zygote
or any of its descendants spawn a process with different bitness due
to the fact that the ASan-RT library name includes the target
architecture.

The fix is to preload the library through a symlink which has the
same name in lib and lib64.

A fake strtol interceptor should at least make forward progress.

This will prevent the check warning the variables which have been
implicitly added by compiler, like the following case (in for-range loop):

Summary:
Set _install_rpath to CMAKE_INSTALL_RPATH if it is defined, so that eventually
INSTALL_RPATH is set to CMAKE_INSTALL_RPATH.
The "if(NOT DEFINED CMAKE_INSTALL_RPATH)" was missing a corresponding else
clause.
This also cleans up the fix made in r285908.

Self-referencing PHI nodes need their destination operands to be constrained
because nothing else is likely to do so. For now we just pick a register class
naively.

Patch mostly by Ahmed again.

We need to apply the same export logic in clang as in llvm for
LLVM_DISTRIBUTION_COMPONENTS, or the clang exports will be invalid
when we use this config.

This makes using distribution components without setting
LLVM_TOOLCHAIN_ONLY=On work correctly.

Codegen prepare sinks comparisons close to a user is we have only one register
for conditions. For AMDGPU we have many SGPRs capable to hold vector conditions.
Changed BE to report we have many condition registers. That way IR LICM pass
would hoist an invariant comparison out of a loop and codegen prepare will not
sink it.

With that done a condition is calculated in one block and used in another.
Current behavior is to store workitem's condition in a VGPR using v_cndmask
and then restore it with yet another v_cmp instruction from that v_cndmask's
result. To mitigate the issue a forward propagation of a v_cmp 64 bit result
to an user is implemented. Additional side effect of this is that we may
consume less VGPRs in a cost of more SGPRs in case if holding of multiple
conditions is needed, and that is a clear win in most cases.

With this we get a new field in the YAML record if the value being
streamed out has a debug location.  For examples, please see the changes
to the tests.

This is then used in opt-viewer to display a link for the callee
function in the inlining remarks.

Summary:
Some vector loads and stores generated from AArch64 intrinsics alias each other
unnecessarily, preventing better scheduling.  We just need to transfer memory
operands during lowering.

ExitOnError is often a better alternative to handleErrors for tool code. This

Summary:
This allows to have clang and llvm and the other subprojects
side-by-side instead of nested. This can be used with the monorepo or
multiple repos.

It will help having a single set of sources checked out but allows to
have a build directory with llvm and another one with llvm+clang.
Basically it abstracts LLVM_EXTERNAL_xxxx_SOURCE_DIR making it more
convenient by adopting a convention.

Because we shift the stack pointer by an unknown amount, we need an
additional pointer. In the case where we have variable-size objects
as well, we can't reuse the frame pointer, thus three pointers.
