…e-trap.ll llvm/test/MC/AArch64/local-bounds-single-trap.ll was introduced in https://github.com/llvm/llvm-project/pull/65972/files to demonstrate that nomerge did not work properly, which is documented in the header comment. llvm#101549 fixed nomerge for trap builtins and llvm@ae6dc64 updated the test assertions, but not the header comment. This patch updates the header comment accordingly.
