The script update_cc_test_checks runs all non-filechecked runlines before the filechecked ones. This creates problems since outputs of those non-filechecked runlines may conflict and that will fail the execution of update_cc_test_checks. This patch executes non-filechecked in the order specified in the test file to avoid this issue.

When the target triple was an Apple platform `ToolChain::getOSLibName()`
(called by `getCompilerRTPath()`) would return the full OS name
including the version number (e.g. `darwin20.3.0`). This is not correct
because the library directory for all Apple platforms is `darwin`.
This in turn caused
* `-print-runtime-dir` to return a non-existant path.
* `-print-file-name=<any compiler-rt library>` to return the filename
instead of the full path to the library.
Two regression tests are included.

This implements the flag proposed in RFC
http://lists.llvm.org/pipermail/cfe-dev/2020-August/066437.html.
The goal is to add a way to override the default target C++ ABI through a
compiler flag. This makes it easier to test and transition between different
C++ ABIs through compile flags rather than build flags.
In this patch:
- Store -fc++-abi= in a LangOpt. This isn't stored in a CodeGenOpt because
there are instances outside of codegen where Clang needs to know what the
ABI is (particularly through ASTContext::createCXXABI), and we should be
able to override the target default if the flag is provided at that point.
- Expose the existing ABIs in TargetCXXABI as values that can be passed
through this flag.
- Create a .def file for these ABIs to make it easier to check flag values.
- Add an error for diagnosing bad ABI flag values.

as used.
The problem only happens with constexpr variable, for constexpr variable,
variable is not marked during parser variable. This is because compiler
might find some var's associate expressions may not actully an odr-used
later, the variables get kept in MaybeODRUseExprs, in normal case, at
end of process fullExpr, the variable will be marked during the call to
CleanupVarDeclMarking(). Since we are processing expression of OpenMP
clauses, and the ActOnFinishFullExpr is not getting called that casue
variable is not get marked.
One way to fix this is to call CleanupVarDeclMarking() in EndOpenMPClause
for each omp directive.

The use of llvm::sort causes periodic failures on the bot with EXPENSIVE_CHECKS enabled,
as the regular sort pre-shuffles the array in the expensive checks mode, leading to a

We weren't modifying the lock set when intersecting with one coming
from a break-terminated block. This is inconsistent, since break isn't a
back edge, and it leads to false negatives with scoped locks. We usually
don't warn for those when joining locksets aren't the same, we just
silently remove locks that are not in the intersection. But not warning
and not removing them isn't right.

The motivation here is to make it available in the base class whether a
fact is managed or not. That would have meant three flags on the base
class, so I had a look whether we really have 8 possible combinations.
It turns out we don't: asserted and declared are obviously mutually
exclusive. Managed facts are only created when we acquire a capability
through a scoped capability. Adopting an asserted or declared lock will
not (in fact can not, because Facts are immutable) make them managed.
We probably don't want to allow adopting an asserted lock (because then
the function should probably have a release attribute, and then the
assertion is pointless), but we might at some point decide to replace a
declared fact on adoption.

MSVC has added some new flags. Although they're not supported, this adds
parsing support for them so clang-cl doesn't treat them as filenames.
Except for /fsanitize=address which we do support. (clang-cl already
exposes the -fsanitize= option, but this allows using the

flag gathering quiet and propagate signaling NaN inputs per IEEE754-2008, which is
conveyed by a function attribute "amdgpu-ieee". "amdgpu-ieee"="false" turns this off.
Without this function attribute backend assumes it is on for compute functions.

By default it is on. -mno-amdgpu-ieee requires -fno-honor-nans or equivalent.
