I originally proposed this rewording when trap reasons were introduced in https://github.com/llvm/llvm-project/pull/145967#discussion_r2196212344. This was not adopted because there was a counter-proposal to split the enum; however, that work appears to have stalled (https://github.com/llvm/llvm-project/pull/151243). In the meantime, there has been an additional datapoint that the current wording is confusing to users. Thus, let's reword it now to prevent further confusion.
