I guess this case hasn't come up thus far, and i'm not sure if it can
really happen for the existing usages, thus no test in *this* commit.
But, the following commit adds test coverage,
there we'd expirience a crash without this fix.
Currently, InsertNoopCastOfTo() would implicitly insert that cast,
but now that we have SCEVPtrToIntExpr, i'm hoping we could stop
InsertNoopCastOfTo() from doing that. But first all users must be fixed.
Move <string> include to ImportedFunctionsInliningStatistics.cpp and add missing <memory> include as we have explicit uses of std::unique_ptr in the header.
These are needed when buildling `clang-format` in a clean build dir.
It's a bit unfortunate that clang's lib/Basic depends on these
random TableGen targets. In the CMake build, this is less visible
because I think all llvm-tblgen's complete before all compiles there
(not sure though).
protectMappedMemory no longer returns an error message, so we don't need std::string - I've fixed an unnecessary doxygen entry as well (oddly I wasn't seeing a Wdocumentation warning)

Expose the debug flag as a readable and assignable property of a
dedicated class instead of a write-only function. Actually test the fact
of setting the flag. Move test to a dedicated file, it has zero relation
to context_managers.py where it was added.
Arguably, it should be promoted from mlir.ir to mlir module, but we are
not re-exporting the latter and this functionality is purposefully
hidden so can stay in IR for now. Drop unnecessary export code.
Refactor C API and put Debug into a separate library, fix it to actually
set the flag to the given value.

This patch extends the lowering of RVV fixed-length vector shuffles to
avoid the default stack expansion and instead lower to vrgather
instructions.
For "permute"-style shuffles where one vector is swizzled, we can lower
to one vrgather. For shuffles involving two vector operands, we lower to
one unmasked vrgather (or splat, where appropriate) followed by a masked
vrgather which blends in the second half.
On occasion, when it's not possible to create a legal BUILD_VECTOR for
the indices, we use vrgatherei16 instructions with 16-bit index types.
For 8-bit element vectors where we may have indices over 255, we have a
fairly blunt fallback to the stack expansion to avoid custom-splitting
of the vector types.
To enable the selection of masked vrgather instructions, this patch
extends the various RISCVISD::VRGATHER nodes to take a passthru operand.

This patch simplifies (and renames) the `appendCommonModuleArguments` function.
It no longer tries to construct the command line for explicitly building modules. Instead, it only performs the DFS traversal of modular dependencies and queries the callbacks to collect paths to `.pcm` and `.modulemap` files.
This makes it more flexible and usable in two contexts:
* Generating additional command line arguments for the main TU in modular build. The `std::vector<std::string>` output parameters can be used to manually generate appropriate command line flags.
* Generate full command line for a module. The output parameters can be the corresponding parts of `CompilerInvocation`. (In a follow-up patch.)

Instead of using a MinVersion and MaxVersion field, encode the version
of a builtin using a mask that aligns better with version handling in
OpenCLOptions.h. In addition, this saves a field in the BuiltinTable.
This change allows a finer-grained control over the OpenCL versions in
which a builtin is available: instead of a range, we can now toggle
each version individually.
The fine-grained version control is not yet exposed on the TableGen
definitions side, as changes for OpenCL 3 feature optionality still
need to be defined and will affect how we want to expose these.
