This fixes issues with various return types(bool/int) and was already
in place for nvptx headers, adjusted to work for amdgcn. This does
not affect hip as the change is guarded with OPENMP_AMDGCN.

Add runtime functions to detect invalid calls to pure or deleted virtual

Add the `memory_scope_all_devices` enum value, which is restricted to
OpenCL 3.0 or newer and the `__opencl_c_atomic_scope_all_devices`
feature. Also guard `memory_scope_all_svm_devices` accordingly, which
is already available in OpenCL 2.0.
The `__opencl_c_atomic_scope_all_devices` feature is header-only, so
set its define to 1 in `opencl-c-base.h`. This is done
unconditionally at the moment, as the mechanism for disabling
header-only options hasn't been decided yet.
This patch only adds a negative test for now. Ideally adding a CL3.0
run line to atomic-ops.cl should suffice as a positive test, but we
cannot do that yet until (at least) generic address spaces and program
scope variables are supported in OpenCL 3.0 mode.

libstdc++ redeclares __failed_assertion multiple times and that results in the
function declared with conflicting set of attributes when we include <complex>
with __host__ __device__ attributes force-applied to all functions.
In order to work around the issue, we rename __failed_assertion within the
region with forced attributes.
See https://bugs.llvm.org/show_bug.cgi?id=50383 for the details.

There are two reasons this shouldn't be restricted to Power8 and up:
1. For XL compatibility
2. Because clang will expand comparison operators to these intrinsics*
*Without this patch, the following causes a selection error:
int test(vector signed long a, vector signed long b) {
return a < b;
}
This patch provides the handling for the intrinsics in the back
end and removes the Power8 guards from the predicate functions
(vec_{all|any}_{eq|ne|gt|ge|lt|le}).
This removed the pointless need for extension pragma since
it doesn't disable anything properly and it doesn't need to
enable anything that is not possible to disable.
The change doesn't break existing kernels since it allows to
compile more cases i.e. without pragma statements but the
pragma continues to be accepted.

To improve hygiene, consistency, and usability, it would be good to replace all
the macro intrinsics in wasm_simd128.h with functions. The reason for using
macros in the first place was to enforce the use of constants for some arguments
using `_Static_assert` with `__builtin_constant_p`. This commit switches to
using functions and uses the `__diagnose_if__` attribute rather than
`_Static_assert` to enforce constantness.
The remaining macro intrinsics cannot be made into functions until the builtin
functions they are implemented with can be replaced with normal code patterns
because the builtin functions themselves require that their arguments are
constants.
This commit also fixes a bug with the const_splat intrinsics in which the f32x4
and f64x2 variants were incorrectly producing integer vectors.

The builtins were updated to take signed parameters in 627a526955, but the
intrinsics that use those builtins were not updated as well. The intrinsic test
did not catch this sign mismatch because it is only reported as an error under
-fno-lax-vector-conversions.
This commit fixes the type mismatch and adds -fno-lax-vector-conversions to the
test to catch similar problems in the future.

This adds additional support for XL compatibility. There are a number
of functions in altivec.h that produce a single instruction (or a
very short sequence) for Power8 but can be done on Power7 without
scalarization. XL provides these implementations.
This patch adds the following overloads for doubleword vectors:
vec_add
vec_cmpeq
vec_cmpgt
vec_cmpge
vec_cmplt
vec_cmple
vec_sl
vec_sr
vec_sra
We do provide `operator delete(void*)` in `<new>` but it should be
available by default. This is mostly boilerplate to test it and the
unconditional include of `<new>` in the header we always in include
on the device.

These intrinsics do not correspond to their own underlying instruction, but are

Update the SIMD builtin load functions to take pointers to const data and update

This adds the long overdue implementations of these functions
that have been part of the ABI document and are now part of
the "Power Vector Intrinsic Programming Reference" (PVIPR).
The approach is to add new builtins and to emit code with

on the command line.

Adds new intrinsics for instructions that are in the final SIMD spec but did not
previously have intrinsics. Also updates the names of existing intrinsics to
reflect the final names of the underlying instructions in the spec. Keeps the
old names as deprecated functions to ease the transition to the new names.

There are some interfaces in altivec.h that are not compatible
between Clang and XL (although Clang is compatible with GCC).
Currently, we have found 3 but there may be others.
Clang/GCC signatures:
vector double vec_ctf(vector signed long long)
vector double vec_ctf(vector unsigned long long)
vector signed long long vec_cts(vector double)
vector unsigned long long vec_ctu(vector double)
XL signatures:
vector float vec_ctf(vector signed long long)
vector float vec_ctf(vector unsigned long long)
vector signed int vec_cts(vector double)
vector unsigned int vec_ctu(vector double)
This patch provides the XL behaviour under the __XL_COMPAT_ALTIVEC__
macro for users that rely on XL behaviour.

These are added for compatibility with XLC. They are similar to
vec_cts and vec_ctu except that the result is a doubleword vector
regardless of the parameter type.

hipRTC compiles HIP device code at run time. Since the system may not
have development tools installed, when a HIP program is compiled through
hipRTC, there is no standard C or C++ header available. As such, the HIP
headers should not depend on standard C or C++ headers when used
with hipRTC. Basically when hipRTC is used, HIP headers only provides
definitions of HIP device API functions. This is in line with what nvRTC does.
This patch adds support of hipRTC to HIP headers in clang. Basically hipRTC
defines a macro __HIPCC_RTC__ when compile HIP code at run time. When
this macro is defined, HIP headers do not include standard C/C++ headers.
