[LoongArch] Drop asm part from memory barrier optimization pass (#223656)
Drop the inline asm part from #218597, which violates inline assembly
semantics.
Fix VM and container duplicate-UUID check for spelling variants
## Problem
`UUIDv4String` did neither thing its name implies. `uuid.UUID(value, version=4)` overwrites the version and variant bits on a throwaway object rather than asserting them, so a v1, v5, v6, v7 or the nil UUID all passed; and the validator returned the caller's original string, so the braced, `urn:uuid:`, uppercase and unhyphenated spellings of one UUID were each stored verbatim.
That made the create-time uniqueness check compare presentation instead of identity — it is a datastore filter, so SQL `=` against a BINARY-collated column — and two rows spelling one UUID differently both got in. Since the uuid is written to both `<name>` and `<uuid>` of the libvirt domain XML and `defineXML` only happens at start, nothing went wrong until the second VM was started, at which point libvirt refused it while quoting the first VM's uuid. `uuid` is immutable after creation, so that row cannot be repaired in place.
## Solution
- **Real version check.** `uuidv4_validator` now parses without `version=` and rejects anything whose `.version` is not 4. The nil and max UUIDs report `None` there, so they are rejected too, and the "not a valid UUID" and "not version 4" cases now report separately instead of sharing one misleading message.
- **A permissive `UUIDString` for the entry models.** The version was never actually enforced in any shipped release, so non-v4 uuids exist in the field. The entry models are what `query` validates stored rows against, and a row that fails there is dropped from the result rather than reported, so tightening them would make those VMs disappear. Strict type on create, permissive type on read. `v26_0_0/vm.py` needed a `VMCreate.uuid` override added, as it was the one model inheriting the annotation from its entry.
- **Compare uuids by value.** New `same_uuid()` in `middlewared/utils/libvirt/utils.py`, used by both `validate()` methods in place of the datastore filter. This cannot be pushed into SQL — a case-insensitive collation still would not equate the unhyphenated form with the hyphenated one — so it reads the rows and folds over them, which is fine at these tables' size.
Deliberately not included: normalising the stored value. Rewriting it renames a libvirt domain out from under a possibly running guest and invalidates the pid and runtime paths derived from it, and once the comparison is by value a non-canonical row stays self-consistent anyway.
CodeGen: Pass instruction and operand index to isPCRelRegisterOperandLegal (#219420)
Replace the MachineOperand argument to the
TargetInstrInfo::isPCRelRegisterOperandLegal hook with the containing
instruction and operand index. The M68k implementation only used the
operand
to recover its parent instruction and operand number, so this drops the
dependence on MachineOperand::getParent().

[flang][OpenMP] Add -fopenmp-version flag to several tests
The default OpenMP version in flang is 3.1. A number of tests use features
added in later versions. They currently pass because the version validity
is not enforced in many cases. Set the OpenMP version explicitly to avoid
failures when the checks become more strict.

2. If any part of the BSD cmsg to Linux cmsg conversion or copyout

close all the file descriptors in it -- otherwise, they would leak
because the user process has no idea it has been given the fds.

biology/vsearch: Update to 2.32.0
Numererous bug fixes, new per-command man pages, and a few other
enhancements.
Changes: https://github.com/torognes/vsearch/releases
Normally I don't upgrade ports so close to the end of a quarter, but
this release has a lot of bug fixes, which I think outweigh the risk
of a regression slipping into the next quarterly branch.
