[CIR][AArch64] Lower NEON vtrn intrinsics (#197651)
### Summary
part of : https://github.com/llvm/llvm-project/issues/185382
lower `vtrn` intrinsics in:
https://arm-software.github.io/acle/neon_intrinsics/advsimd.html#transpose-elements
Lower `case NEON::BI__builtin_neon_vtrn_v` and `case
NEON::BI__builtin_neon_vtrnq_v` CIRGenBuiltinAArch64.cpp by porting by
porting the existing incubator
logic(`clangir/clang/lib/CIR/CodeGen/CIRGenBuiltinAArch64.cpp`),generating
the two transpose results with `cir.vec.shuffle`, and storing both
vectors into the returned pair structure.
All intrinsics in `clang/test/CodeGen/AArch64/neon-perm.c` have been
migrated into `clang/test/CodeGen/AArch64/neon/perm.c`,so I delete the
original file.
[IR] Verify that VP !prof does not have duplicate prof values
Follows on #193077. We should not have duplicate values as they should
be merged before being moved into IR. Add this to the verifier so that
we can actually enforce this constraint.

[flang][OpenMP] Add diagnostic for bare DECLARE TARGET in invalid scopes (#198039)
The bare form of `!$omp declare target` (without arguments or clauses)
is only permitted in the specification part of a subroutine, function,
or interface body (OpenMP 5.2, section 7.8.2). Flang previously accepted
it silently in BLOCK DATA, PROGRAM, MODULE, SUBMODULE, and BLOCK
constructs.
This patch:
- Adds a semantic check rejecting the bare form outside Subprogram
scopes.
- Adds MpSubprogramStmt/EndMpSubprogramStmt scope tracking to avoid
false positives in separate module subprograms (MODULE PROCEDURE).
- Fixes pre-existing BlockConstruct scope tracking bugs: the Leave
handler was pushing instead of popping (stack corruption), and the
Enter handler used blockStmt.source which resolves to the parent
scope. Now uses endBlockStmt.source (walked inside the block scope
during name resolution) for correct BlockConstruct scope identity.

nfsd: Disable use of callbacks for NFSv4.0
Commit 71ac1ec5c9d9 disabled callbacks for the NFS
client for NFSv4.0. This patch does the same for
the NFSv4.0 server.
The only use for callbacks for NFSv4.0 is delegations
and delegations rarely work well for NFSv4.0 anyhow.
Therefore, this patch disables callbacks for the
NFSv4.0 server. This is the same behavior as
occurs when vfs.nfsd.issue_delegations is 0.
This change allowed the functions called
nfsrv_getclientipaddr() and nfsrv_getipnumber() to be
removed from the kernel.
