If this causing significant issues with OOM / timeout, I'm open to reverting for now and finding a more efficient approach (I'm proposing one in https://github.com/llvm/llvm-project/pull/75258).

Do you have any data that suggests why the previous fix (https://github.com/llvm/llvm-project/pull/75218) didn't solve the problem? Was it generating super long fused locations? Or was it just due to all the temporary fused locations that were created since we "append" locations incrementally?
