[MLIR][LLVM] Reject distinct generic metadata on import (#212455)

Reject distinct nodes when converting generic LLVM metadata into LLVM
dialect attributes because `MDNodeAttr` cannot preserve node identity.
Apply the policy recursively so top-level and nested nodes use the
existing unsupported-metadata failure path while finite acyclic uniqued
nodes remain importable.

Git commit 610a3105af18f5efd127d2eaa1e4633de830b593 by GitHub (on behalf of Akimasa Watanuki) on 01/08/2026 at 13:08..
[MLIR][LLVM] Share LLVM metadata attribute translation (#203016)

Share LLVM dialect metadata materialization through `ModuleTranslation`
so named metadata and metadata-as-value lowering use one conversion
path. Resolve metadata symbol references to functions, globals, aliases,
and ifuncs, and diagnose malformed required metadata before lowering.

Rename `MDFuncAttr` to `MDGlobalValueAttr` to reflect its support for
symbol-backed global values.

[MLIR][LLVM] Preserve global value metadata operands on import

Import global value references inside LLVM metadata operands as LLVM dialect metadata symbol-reference attributes. Add llvm.read_register import coverage for function, global, alias, and nameless-global metadata operands.
