Yingwei Zheng b4bb2f8aef [LoopDeletion] Unblock loop deletion with llvm.experimental.noalias.scope.decl (#108144) ...

Since `llvm.experimental.noalias.scope.decl` is marked as
`memory(inaccessiblemem: readwrite)`, we cannot treat this annotation
intrinsic as having no side effects. It will block loop deletion when
this intrinsic exists inside a dead loop:

3dad29b677/llvm/lib/Transforms/Scalar/LoopDeletion.cpp (L103-L110)

This patch marks `llvm.experimental.noalias.scope.decl` as droppable to
address the issue.

Fixes https://github.com/llvm/llvm-project/issues/108052.
