a5377240 - [LLVM][DAGCombine] Remove combiner-vector-fcopysign-extend-round. (#129878)

[LLVM][DAGCombine] Remove combiner-vector-fcopysign-extend-round. (#129878) This option was added to improve test coverage for SVE lowering code that is impossible to reach otherwise. Given it is not possible to trigger a bug without it and the generated code is universally worse with it, I figure the option has no value and should be removed.
