    [PR119021][LRA]: Fix rtl correctness check failure in LRA.
    
      Patch to fix PR115458 contained a code change in dealing with asm
    errors to avoid cycling in reporting the error for asm gotos.  This
    code was wrong and resulted in checking RTL correctness failure.  This
    patch reverts the code change and solves cycling in asm error
    reporting in a different way.
    
    gcc/ChangeLog:
    
            PR middle-end/119021
            * lra.cc (lra_asm_insn_error): Use lra_invalidate_insn_data
            instead of lra_update_insn_regno_info.
            * lra-assigns.cc (lra_split_hard_reg_for): Restore old code.
