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.
Call df_notes_rescan if that argument is not true and returning
true.
* combine.c (adjust_for_new_dest): Pass true as second argument to
remove_reg_equal_equiv_notes.
* postreload.c (reload_combine_recognize_pattern): Don't call
df_notes_rescan.
