* config/alpha/alpha.c (some_small_symbolic_operand,
        some_small_symbolic_operand_1, split_small_symbolic_operand,
        split_small_symbolic_operand_1): Rename from *symbolic_mem_op*.
        Handle small SYMBOL_REFs anywhere, not just inside memories.
        * config/alpha/alpha-protos.h: Update.
        * config/alpha/alpha.h (PREDICATE_CODES): Update.
        * config/alpha/alpha.md (small symbolic operand splitter): Update.
