ENTRY point symbols aren't marked PURE in the symbol table, but must
instead inherit the attribute from their containing subprograms.
There's a predicate in semantics that does this, but it wasn't being
used in the context of actual procedure argument characterization.

The LDMX instruction was to be potentially added in P9 but it was never added
in either ISA 3.0 or ISA 3.1. This patch removes that instruction as it is

The predicate IsInitialDataTarget() was failing to return a correct true
result in the case of a reference to the intrinsic function NULL() with a
MOLD= argument. Fix, and improve tests for "NULL()" elsewhere in semantics,
checking for an attribute set by intrinsics.cpp rather than the actual name.

The texsurf_handle is removed by NVPTXReplaceImageHandles.cpp. There are more than one uses of the texsurf_handle, one of them is a regular function call, and one of them is a texture intrinsic.
The current hacky logic in NVPTXReplaceImageHandles.cpp for CUDA cannot handle such a mixed use. This patch fixes this issue.

These global TLS symbols are shared across all shared libraries and
therefor should not be assumed to be local to the current module.
Also add new error in the linker when TLS relocations are used against
undefined symbols. TLS relocations are offsets into the current modules
tls data segment, and don't make sense for undefined symbols which are
modeled as global imports.

There was a fixme in the code pertaining to attributing functions as
noreturn. By using reachability, if none of the blocks that are
reachable from the entry return, then the function is noreturn.
Previously, the code only checked if any blocks returned. If they're
unreachable, then they don't matter.
This improves codegen for the Linux kernel.

An enum value stores the offset between AGPR ranges and VGPR
ranges in the internal storage of SIInsertWaitcnts. It said 226 when
it should say 256, causing some portion of the ranges to overlap. That
in turn causes 'aliasing' between the registers, potentially inserting
waitcnts that are not required.

We added one for libc++ recently, and this patch adds one for libc++abi.
Also, as a fly-by fix, include older libunwind dylibs in the testing of

Currently whenever we compile the device runtime we get the following
'Mapping.cpp:32:32: warning: inline function '_OMP::impl::getGridValue'
is not defined [-Wundefined-inline]' warning. This can be silenced by
removing the constexpr attribute for this function. Doing this doesn't
change the generated bitcode at all but prevents the screen from getting
filled with warnings whenver we build the runtime.

This patch allows the lowring of simple empty function with a
scalar integer or logical return value.
The code in ConvertType.cpp is cleaned up as well. This file was landed
together with the initial flang push and lowering was still a prototype

This patch extends clang driver to pass the right flags to the clang frontend, and ld64,
so that they can emit macho files with two build version load commands. It adds a new
0darwin-target-variant option which complements -target and also can be used to specify different
target variants when multi-arch compilations are invoked with multiple -arch commands.

This fixes warnings about implicitly declared `_umul128` and
`__shiftright128` when building for x86_64 with clang-cl.
Use `_MSC_VER` instead of `_LIBCPP_COMPILER_MSVC` for enabling MSVC
specific code; `_MSC_VER` is defined both in clang-cl and MSVC,
while `_LIBCPP_COMPILER_MSVC` only is defined if building with the
actual MSVC compiler.
Include `ryu.h` at the head of `d2s_intrinsics.h`, as it uses
the `_LIBCPP_64_BIT` define, which is defined in `ryu.h`.
Now the Ryu files build without warnings with clang-cl for i386,
x86_64, arm and aarch64.

This introduces a new "ptrauth" operand bundle to be used in
call/invoke. At the IR level, it's semantically equivalent to an
@llvm.ptrauth.auth followed by an indirect call, but it additionally
provides additional hardening, by preventing the intermediate raw
pointer from being exposed.
This mostly adds the IR definition, verifier checks, and support in
a couple of general helper functions. Clang IRGen and backend support
will come separately.
Note that we'll eventually want to support this bundle in indirectbr as
well, for similar reasons. indirectbr currently doesn't support bundles
at all, and the IR data structures need to be updated to allow that.
