This applies the same fix as in `ad3870d6`
for `TestRerunAndExpr.py` to this test.

The arguments to a PHI may represent a recurrence by eventually using the output
of the PHI itself. This is now handled by checking for cycles in the control
flow. If a PHI is not in a recurrence, it is now able to report multiple offsets
instead of conservatively reporting unknown.

As far as I can tell m_riscv_Features_Group is for options that
can be passed to cc1's -target-feature. These mcmodel aliases aren't
that.

I think they get treated as aliases and disappear before we get
to processing m_riscv_Features_Group so it didn't cause any problems.

I've left them in m_Group to match mcmodel_EQ.

We don’t have W versions of AND/OR/XOR/ANDN/ORN/XNOR so we should recursively check their users. We should limit the recursion to SelectionDAG::MaxRecursionDepth levels.

We need to add a Depth argument, all existing callers should pass 0 to the Depth. The new recursive calls should increment it by 1. At the top of the function we should give up and return false if Depth >= SelectionDAG::MaxRecursionDepth.

llvm::Optional<T> has transform, which is equivalent to
std::optional<T>::transform.  The problem is that
std::optional<T>::transform won't be available until C++23, implying
that we probably cannot use it in our codebase untli 2028 or so.  We
certainly don't want to keep llvm::Optional just for transform.

This patch adds llvm::transformOptional to STLForwardCompat.h so that
we can use transform during the migration to std::optional and beyond.

I've shamelessly borrowed the implementation and test from
llvm/include/llvm/ADT/Optional.h and
llvm/unittests/ADT/OptionalTest.cpp respectively.

This adds some SPARC feature flags to clang, for those that we have in common with GCC:

-m[no-]fsmuld
-m[no-]popc
-m[no-]vis
-m[no-]vis2
-m[no-]vis3
-m[hard/soft]-quad-float

All have the same meanings as GCC's options (https://gcc.gnu.org/onlinedocs/gcc/SPARC-Options.html).

**Summary**

Starting with DWARFv5, DW_AT_default_value can be used to indicate
that a template argument has a default value. With this patch Clang
will attach the attribute to the debug metadata regardless of version.

In a follow-up patch we will change llvm to emit this attribute in
earlier versions of DWARF, unless compiling with -gstrict-dwarf.

**Details**

* Previously the DwarfVersion check in CGDebugInfo was inconsistent:
  For non-type template arguments we attached the attribute to the debug
  metadata in DWARFv5 only. Whereas for type template arguments we didn't
  have such a version restriction. With this patch we attach the attribute
  regardless of DWARF version (and instead offload the check to the AsmPrinter
  in a future patch).

This allows allocaBuffer to be used outside of SparseTensorConversion.cpp, which will be helpful for a some future commits.

assumes an instruction is already predicated and returns true if it can

iterate multiple times on architectures supporting predicate logic.

No test added since there is no upstream target that can take advantage.
