By default the RISC-V target doesn't have the atomics standard extension
enabled. The first RUN line in `clang/test/CodeGen/atomic_ops.c` didn't
specify a target triple, which meant that on RISC-V Linux hosts it would
target RISC-V, but because it used clang cc1 we didn't get the toolchain
driver functionality to automatically turn on the extensions implied by
the target triple (riscv64-linux includes atomics). This would cause the
test to fail on RISC-V hosts.
This patch changes the test to have RUN lines for two explicit targets,
one with native atomics and one without. To work around FileCheck
limitations and more accurately match the output, some tests now have
separate prefixes for the two cases.

It is generally preferable to avoid name collision with system headers
(reducing reliance on -isystem order, more friendly when navigating files in

while that is certainly UB land, it may not be actually reachable at runtime, e.g.:
```
template<int N> void *make() {
if ((N & (N-1)) == 0)
return operator new(N, std::align_val_t(N));
else
return operator new(N);
}
void *p = make<7>();
```
and we shouldn't really error-out there.
That being said, i'm not really following the logic here.
Which ones of these cases should remain being an error?

This commit removes the artificial types <512 x i1> and <1024 x i1>
from HVX intrinsics, and makes v512i1 and v1024i1 no longer legal on
Hexagon.
It may cause existing bitcode files to become invalid.
* Converting between vector predicates and vector registers must be
done explicitly via vandvrt/vandqrt instructions (their intrinsics),
i.e. (for 64-byte mode):
%Q = call <64 x i1> @llvm.hexagon.V6.vandvrt(<16 x i32> %V, i32 -1)
%V = call <16 x i32> @llvm.hexagon.V6.vandqrt(<64 x i1> %Q, i32 -1)
The conversion intrinsics are:
declare <64 x i1> @llvm.hexagon.V6.vandvrt(<16 x i32>, i32)
declare <128 x i1> @llvm.hexagon.V6.vandvrt.128B(<32 x i32>, i32)
declare <16 x i32> @llvm.hexagon.V6.vandqrt(<64 x i1>, i32)
declare <32 x i32> @llvm.hexagon.V6.vandqrt.128B(<128 x i1>, i32)
They are all pure.
* Vector predicate values cannot be loaded/stored directly. This directly
reflects the architecture restriction. Loading and storing or vector
predicates must be done indirectly via vector registers and explicit
conversions via vandvrt/vandqrt instructions.
This patch introduces a new helper class `OMPBuilderCBHelpers`,
which will contain all reusable C/C++ language specific function-
alities required by the `OMPIRBuilder`.
Initially, this helper class contains the body and finalization
codegen functionalities implemented using callbacks which were
moved here for reusability among the different directives
implemented in the `OMPIRBuilder`, along with RAIIs for preserving
state prior to emitting outlined and/or inlined OpenMP regions.
In the future this helper class will also contain all the different
call backs required by OpenMP clauses/variable privatization.

WG21 considers the C++20 standard to be finished (even though it still

The old flag names are accepted for compatibility, as usual, and we

those can be cleaned up separately.
Summary:
$ clang -O2 -pg -mfentry foo.c
was adding frame pointers to all functions. This was exposed via
compiling the Linux kernel for x86_64 with CONFIG_FUNCTION_TRACER
enabled.
-pg was unconditionally setting the equivalent of -fno-omit-frame-pointer,
regardless of the presence of -mfentry or optimization level. After this
patch, frame pointers will only be omitted at -O0 or if
-fno-omit-frame-pointer is explicitly set for -pg -mfentry.

The standard wording doesn't really cover these cases; accepting all

other compilers do. (Essentially this means we're assuming that objects
