[Clang] Transform SubstNonTypeTemplateParmExpr replacements in a constant-evaluated context (#196791)
Fixes #175831.
When transforming a `SubstNonTypeTemplateParmExpr`,
`TreeTransform::TransformSubstNonTypeTemplateParmExpr` calls
`Sema::CheckTemplateArgument` so that any sema annotations (such as
implicit casts) that were stripped from the replacement are recovered.
This is done in whatever evaluation context the node happens to appear
in after substitutions.
Since the normalization of constraints, a `SubstNonTypeTemplateParmExpr`
can end up inside an unevaluated operand, so the replacement gets
rebuilt in an unevaluated context.
Entities it refers to are then not odr-used: for example, when a call
materializes a by-value function parameter of class type, the copy
constructor is never marked odr-used and its definition is never
instantiated.
The constant evaluation performed by `CheckTemplateArgument` afterwards

fwcam: add IIDC 1394 FireWire camera driver
Add fwcam(4), a driver for IIDC v1.30 (TA Document 1999023) digital
cameras over IEEE 1394.
Supports Format_0 (VGA) video modes with isochronous receive DMA,
feature control (brightness, exposure, gain, shutter, white balance,
focus, etc.), poll/kqueue, and hot-plug via bus reset handling.

[MLIR][XeGPU] Fix order remapping in layout transpose (#205212)
LayoutAttr::transposeDims and LayoutAttr::isTransposeOf mishandled the
`order` field when transposing a layout. The `order` field is
fundamentally different from the size-valued fields (sg_layout, sg_data,
inst_data, lane_layout, lane_data): its values are dimension indices
(order[0] is the fastest-varying dim), not per-position sizes. The two
require different transpose rules:
- Size fields — reindex by position: new[i] = orig[perm[i]]
- order — relabel values through the inverse permutation: newOrder[i] =
inversePerm[origOrder[i]]
Both functions incorrectly applied the size-field rule to `order`.
Because the bug was applied consistently in both places, it stayed
hidden for trivial/symmetric (e.g. 2D [1,0]) permutations, where the two
rules happen to coincide. It only surfaces for non-trivial permutations
such as the 3D [1,0,2] produced by a broadcast→transpose chain.

[RISCV] Emit .option arch extensions without the "experimental-" prefix (#205471)
We currently emit the "experimental-" prefix in .option arch, e.g.
`.option arch, +experimental-zicfiss`, but the assembler can't parse
that back.
There are two ways to fix this:
1. Teach the assembler to accept `.option arch, +experimental-zicfiss`.
2. Emit `.option arch, +zicfiss` instead of `.option arch,
+experimental-zicfiss`.
This patch takes the second approach, which better fits the .option arch
syntax we defined. Experimental extensions are still guarded by
`-menable-experimental-extensions`.
nfs_clvnops.c: Fix the case where va_flags are being cleared
Commits c5d72d2 and 3b6d4c6 broke the case where the
archive/hidden/system attributes are being set false
(UF_ARCHIVE, UF_HIDDEN or UF_SYSTEM bits being cleared.)
and the NFS server does not support those attributes.
These patches only checked for support if the
archive/hidden/system attributes were non-zero.
This patch fixes the problem.
