Jan Svoboda 0a92e09c07 [clang][deps] Generate the full command-line for modules
This patch uses the new `CompilerInvocation::generateCC1CommandLine` to generate the full canonical command line for modular dependencies, instead of only appending additional arguments.

Tobias Gysi 495e1d7e8a [mlir][linalg] adding pass to run the interchange pattern.
Instead of interchanging loops during the loop lowering this pass performs the interchange by permuting the indexing maps. It also updates the iterator types and the index accesses in the body of the operation.

Fraser Cormack c9a93c3e01 [RISCV] Lower vector shuffles to vrgather operations
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.

Jan Svoboda 32219c8c44 [clang][deps] Simplify function discovering .pcm and .modulemap files
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.)

Sven van Haastregt 6cb7631df3 [OpenCL] Change OpenCL builtin version encoding
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.
