Do not emit call to llvm.dbg.declare when the variable declaration is a DecompositionDecl as its instance class is always unnamed. The emitted debug declare looks like: call void @llvm.dbg.declare(metadata ..., metadata !xx, metadata ...) !xx = !DILocalVariable(scope: !..., file: !..., line: ..., type: !...)
