The final.c, genattrtab.c, and tree.c hunks are ok.
The strcpy bits I'd like to have handled differently.
(1) Rename the existing rtl movstr patterns to movmem.
(2) Create new movstr patterns that mirror how cmpstr patterns operate.
(3) Expand strcpy/strpcpy like we do strcmp elsewhere in builtins.c.
