[mlir] Fix RemoveDeadRegionBranchOpSuccessorInputs producing invalid scf.for
RemoveDeadRegionBranchOpSuccessorInputs builds its tied-value sets from
RegionBranchOpInterface::getSuccessorOperandInputMapping, which is derived from
getSuccessorRegions. For an scf.for with a statically-known trip count of 1,
getSuccessorRegions drops the region->region back edge (the loop provably never
iterates back). That back edge is what forwards a yield operand to the region
iter_args, so without it an iter_arg and its corresponding op result are no
longer tied through a shared operand. The pattern then removes a dead iter_arg
without its (structurally required) result, producing an scf.for with
mismatched loop-carried counts:
'scf.for' op mismatch in number of loop-carried values and defined values
The greedy driver repairs this on a later iteration (InlineRegionBranchOp folds
the single-trip loop), so it is only observed with
MLIR_ENABLE_EXPENSIVE_PATTERN_API_CHECKS, which verifies the IR after every
pattern application. It shows up across Linalg tiling / pack-unpack /
convolution lowering and scf loop canonicalization; see issue #163599.

RuntimeLibcalls: Provide fp128 long double libcalls on X86
16a8d8d038a3 removed the l-suffixed long double math functions
from the default set and re-added them per-target gated on
isLongDoubleF128, but X86 was not given the re-add. On targets
whose long double is fp128 (e.g. x86_64 Android/OHOS) this dropped
the fp128 l-suffixed libcalls.
Fixes the regression reported on #214944.

multimedia:{ffmpeg,handbrake}: Switch dependency from onevpl to libvpl
onevpl has been superceded by libvpl upstream. So switch dependencies
of dependent ports.

multimedia/libvpl: New port: Intel Video Processing Library API, dispatcher, and examples
Intel Video Processing Library (Intel VPL) provides access to hardware
accelerated video decode, encode, and processing capabilities on Intel GPUs
to support AI visual inference, media delivery, cloud gaming, and virtual
desktop infrastructure use cases.
This repository contains the following components:
- Copies of the Intel VPL API header files.
The version of the API is listed in the mfxdefs.h file.
- Intel VPL Dispatcher
- Examples demonstrating API usage
*** IMPORTANT ***
Intel VPL Tools are no longer in this repository. They have all been
moved to libvpl-tools.

sys/lockdebug.h: Simplify conditional and explain why it's there.
No functional change intended: just changes an always-false
expression to another always-false expression in a conditional.
(Well, in principle, it reduces the number of times we evaluate this
argument, but in practice the argument should be side-effect-free
anyway.)

igc: Correct hardware error statistics
Track RERC separately instead of adding receive errors to the collision
count, and read the previously omitted RXERRC register. Include RFC in
input errors because CRCERRS does not count bad-CRC runts, implementing
the I225 length-error accounting workaround alongside RUC and ROC.
Stop treating host transmit MAC discards as receive errors. Expose both
RERC and HTDPMC as dedicated MAC statistics so their overlapping counts
remain available without corrupting aggregate interface counters.

igc: Work around I225 v1 minimum IPG erratum
I225 v1 cannot receive the minimum inter-packet gap required at
2.5 Gb/s. For affected back-to-back links, Intel recommends using a
15-byte transmit IPG instead of 12 bytes.
Program TIPG.IPGT to 0xb for pre-v2 I225 devices at 2.5 Gb/s and
restore the default at lower speeds. Avoid penalizing fixed I225 and
I226 parts.
