PR rtl-optimization/39794
* alias.c (canon_true_dependence): Add x_addr argument.
* rtl.h (canon_true_dependence): Adjust prototype.
* cse.c (check_dependence): Adjust canon_true_dependence callers.
* cselib.c (cselib_invalidate_mem): Likewise.
* gcse.c (compute_transp): Likewise.
* dse.c (scan_reads_nospill): Likewise.
(record_store, check_mem_read_rtx): Likewise. For non-const-or-frame
addresses pass base->val_rtx as mem_addr, for const-or-frame addresses
canon_base_addr of the group, plus optional offset.
(struct group_info): Rename canon_base_mem to
canon_base_addr.
(get_group_info): Set canon_base_addr to canon_rtx of base, not
canon_rtx of base_mem.
* gcc.dg/pr39794.c: New test.
