re PR middle-end/78540 (ICE: in df_refs_verify, at df-scan.c:4062 with -O -march=core2)
PR middle-end/78540
* rtl.h (remove_reg_equal_equiv_notes): Return bool instead of void.
* rtlanal.c (remove_reg_equal_equiv_notes): Return true if any
note has been removed.
* postreload.c (reload_combine_recognize_pattern): If
remove_reg_equal_equiv_notes returns true, call df_notes_rescan.
* gcc.dg/pr78540.c: New test.
