rtl-optimization/117467 - 33% compile-time in rest of compilation
ext-dce uses TV_NONE, that's not OK for a pass taking 33% compile-time.
The following adds a timevar to it for proper blaming.
PR rtl-optimization/117467
* timevar.def (TV_EXT_DCE): New.
* ext-dce.cc (pass_data_ext_dce): Use TV_EXT_DCE.
