Joe Nash c87c61c52c [AMDGPU] Fix AGPR offset for waitcnt
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.

Joseph Huber 48e3dcecc4 [Libomptarget][NFC] Remove constexpr to hide warnings
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.

[flang] Lower basic function with scalar integer/logical return value
This patch allows the lowring of simple empty function with a

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
at that time. Some more cleaning will come with follow up patches.

This patch is part of the upstreaming effort from fir-dev branch.

This patch extends clang driver to pass the right flags to the clang frontend, and ld64,

Martin Storsjö 7b89360d3a [libcxx] Fix setup of MSVC specific intrinsics in Ryu code
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.

Ahmed Bougacha c703f852c9 [IR] Define "ptrauth" operand bundle.
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.
