Make the empty headers used by cl-pch-showincludes.cpp unique so that

This was uncovered by

an underlying issue that the filename of multiple includes of linked

[RISCV][InsertVSETVLI] Default to MA not MU
This changes the default value used for mask policy from mask undisturbed to mask agnostic. In hardware, there may be a minor preference for ta/ma, but since this is only going to apply to instructions which don't use the mask policy bit, this is functionally mostly a nop. The main value is to make future changes to using MA when legal for masked instructions easier to review by reducing test churn.
The prior code was motivated by a desire to minimize state transitions between masked and unmasked code. This patch achieves the same effect using the demanded field logic (landed in afb45ff), and there are no regressions I spotted in the test diffs. (Given the size, I have only been able to skim.) I do want to call out that regressions are possible here; the demanded analysis only works on a block local scope right now, so e.g. a tight loop mixing masked and unmasked computation might see an extra vsetvli or two.

[mlir][nvgpu] NFC - move NVGPU conversion helpers to NvGpu utils library
The ConvertVectorToGpu pass implementation contained a small private
support library for performing various calculations during conversion
between `vector` and `nvgpu.mma.sync` and `nvgpu.ldmatrix` operations.
The support library is moved under `Dialect/NVGPU/Utils` because the
functions have wider utility. Some documentation comments are added or
improved.

[mlir][sparse] Adjusting DimLevelType numeric values for faster predicates
This differential adjusts the numeric values for DimLevelType values: using the low-order two bits for recording the "No" and "Nu" properties, and the high-order bits for the formats per se. (The choice of encoding may seem a bit peculiar, since the bits are mapped to negative properties rather than positive properties. But this was done in order to preserve the collation order of DimLevelType values. If we don't care about collation order, then we may prefer to flip the semantics of the property bits, so that they're less surprising to readers.)
Using distinguished bits for the properties and formats enables faster implementation for the predicates detecting those properties/formats, which matters because this is in the runtime library itself (rather than on the codegen side of things). This differential pushes through the changes to the enum values, and optimizes the basic predicates. However it does not optimize all the places where we check compound predicates (e.g., "is compressed or singleton"), to help reduce rebasing conflict with D134933. Those optimizations will be done after this differential and D134933 are landed.

[clang-offload-bundler] extracting compatible bundle entry
In HIP a library is usually compiled with default target ID e.g. gfx906 so that
it can be used in all GPU configurations. The bitcode is saved in bundled
bitcode with gfx906 in entry ID.
In runtime compilation, a HIP program is compiled with a target ID matching
the GPU configuration, e.g. gfx906:xnack-. This program needs to link with
a library bundled bitcode with target ID gfx906.
For example:
clang --offload-arch=gfx906 -o lib.o lib.hip
clang --offload-arch=gfx906:xnack- program.hip lib.o
This common use case requires that clang-offlod-bundler to be able to extract
entry with compatible target ID, e.g. extracting an gfx906 entry when requesting
gfx906:xnack-.
Currently clang-offload-bundler only allow extracting entry with exact match
of target ID. This patch relaxes that so that it can extract entries with compatible
target ID.

[clang][deps] Canonicalize module map path
When dep-scanning, canonicalize the module map path as much as we can.
This avoids unnecessarily needing to build multiple versions of a module
due to symlinks or case-insensitive file paths.
Despite the name `tryGetRealPathName`, the previous implementation did
not actually return the realpath most of the time, and indeed it would
be incorrect to do so since the realpath could be outside the module
directory, which would have broken finding headers relative to the
module.
Instead, use a canonicalization that is specific to the needs of
modulemap files (canonicalize the directory separately from the
filename).

[RISCV][ISel] Fold extensions when all the users can consume them
This patch allows the combines that fold extensions in binary operations
to have more than one use.
The approach here is pretty conservative: if all the users of an
extension can fold the extension, then the folding is done, otherwise we
don't fold.
This is the first step towards avoiding the one-use limitation.
As a result, we make a decision to fold/don't fold for a web of
instructions. An instruction is part of the web of instructions as soon
as it consumes an extension that needs to be folded for all its users.
Because of how SDISel works a web of instructions can be visited over
and over. More precisely, if the folding happens, it happens for the
whole web and that's the end of it, but if the folding fails, the whole
web may be revisited when another member of the web is visited.
To avoid a compile time explosion in pathological cases, we bail out
earlier for webs that are bigger than a given threshold (arbitrarily set
at 18 for now.) This size can be changed using
`--riscv-lower-ext-max-web-size=<maxWebSize>`.
At the current time, I didn't see a better scheme for that. Assuming we
want to stick with doing that in SDISel.
