[Bug rtl-optimization/29858] New: regmove has been silently disabled


discover_flag_regs has bitrotted when rtl generation was changed to
emit entire insns instead of patterns.
Hence, any evaulation of the effectiveness of the regmove pass, or
of the impact of changes to the regmove pass to generated code,
is invalid, since the pass does not run at all.
