    csa: Fix --enable-checking=yes,df bootstrap failure in csa [PR94961]

    My recent combine-stack-adj.c change broke df checking bootstrap,
    while most of the changes are done through validate_change/confirm_changes
    which update df info, the removal of REG_EQUAL notes didn't update df info.

            * rtl.h (remove_reg_equal_equiv_notes): Add a bool argument
defaulted
            to false.
            * rtlanal.c (remove_reg_equal_equiv_notes): Add no_rescan argument.

true.
