requirements in protocol/class/category declarations
The unguarded availability warnings in the protocol requirements of a protocol
/class/category declaration can be avoided. This matches the behaviour of
Swift's diagnostics. The warnings for deprecated/unavailable protocols are
preserved.

Summary:
Most clang tools should ignore the -M
family of options because one wouldn't want them
to generate a new dependency (.d) file. However,
some tools may want this dependency file. This
patch creates a mechanism for them to do this.
This implementation just plumbs a boolean down
several layers of calls. Each of the modified calls
has several call sites, and so a single member
variable or new API entry point won't work.
An alternative would be to write a function to filter
the -M family of arguments out of CC1Args, and have
each caller call that function by hand before calling
newInvocation, Invocation::run, or buildAstFromCodeWithArgs.
This is a more complicated and error-prone solution.
Why burden all the callers to remember to use
this function?
But I could rewrite this patch to use that method if
that is deemed more appropriate.

problems in testing, see comments in D34161 for some more details.
A fix is in progres in D35011, but a revert seems better now as the fix will
probably take some more time to land.

Summary: Pass the type of the device offloading when building the tool chain for a particular target architecture. This is required when supporting multiple tool chains that target a single device type. In our particular use case, the OpenMP and CUDA tool chains will use the same ```addClangTargetOptions ``` method. This enables the reuse of common options and ensures control over options only supported by a particular tool chain.

When enable_if disables a particular overload resolution candidate,
rummage through the enable_if condition to find the specific condition
that caused the failure. For example, if we have something like:
template<
typename Iter,
typename = std::enable_if_t<Random_access_iterator<Iter> &&
Comparable<Iterator_value_type<Iter>>>>
void mysort(Iter first, Iter last) {}
and we call "mysort" with "std::list<int>" iterators, we'll get a
diagnostic saying that the "Random_access_iterator<Iter>" requirement
failed. If we call "mysort" with
"std::vector<something_not_comparable>", we'll get a diagnostic saying
that the "Comparable<...>" requirement failed.

This moves determination of the ISA revision from the CPU name to
one single place, removing a bunch of duplicated code. It also
makes the supported ISA revisions available as feature strings.
No functional change.

These cases occur frequently for declarations in the global module (above the
module-declaration) in a Modules TS module interface. When we merge a
definition from another module into such a module-private definition, ensure
that we transitively make everything lexically within that definition visible
to that translation unit.

In C mode clang fails to merge the textually included definition with the one imported from a module. The C lookup rules fail to find the imported definition because its linkage is internal in non C++ mode.
This patch reinstates some of the ODR merging rules for typedefs of anonymous tags for languages other than C++.
Patch by Raphael Isemann and me (D34510).

Combined directives like 'target parallel' have two captured statements.
Sema has to check the right one from the right direction.
Previously, Sema::IsOpenMPCapturedByRef would return false for mapped
scalars on combined directives. This results in a wrong signature of
the outlined function which triggers an assertion:
void llvm::CallInst::init(llvm::FunctionType *, llvm::Value *, ArrayRef<llvm::Value *>, ArrayRef<OperandBundleDef>, const llvm::Twine &): Assertion `(i >= FTy->getNumParams() || FTy->getParamType(i) == Args[i]->getType()) && "Calling a function with a bad signature!"' failed.
Fixes PR30975 (and PR31985). New function was taken from clang-ykt.

Summary:
Depends on https://reviews.llvm.org/D34867.
Add a Clang frontend option to enable optimization remark hotness
thresholds, which were added to LLVM in https://reviews.llvm.org/D34867.
This prevents diagnostics that do not meet a minimum hotness
threshold from being output. When generating optimization remarks for large
codebases with a ton of cold code paths, this option can be used
to limit the optimization remark output at a reasonable size.
