Replace slow byte-oriented tests in several string benchmarks with the generic implementations from the string/ directory so the comparisons are more realistic and useful. * benchtests/bench-stpcpy.c (SIMPLE_STPCPY): Remove function. (generic_stpcpy): New function. * benchtests/bench-stpncpy.c (SIMPLE_STPNCPY): Remove function. (generic_stpncpy): New function. * benchtests/bench-strcat.c (SIMPLE_STRCAT): Remove function. (generic_strcat): New function. * benchtests/bench-strcpy.c (SIMPLE_STRCPY): Remove function. (generic_strcpy): New function. * benchtests/bench-strncat.c (SIMPLE_STRNCAT): Remove function. (STUPID_STRNCAT): Remove function. (generic_strncat): New function. * benchtests/bench-strncpy.c (SIMPLE_STRNCPY): Remove function. (STUPID_STRNCPY): Remove function. (generic_strncpy): New function. * benchtests/bench-strnlen.c (SIMPLE_STRNLEN): Remove function. (generic_strnlen): New function. (memchr_strnlen): New function. * benchtests/bench-strlen.c (generic_strlen): Define for WIDE. (memchr_strlen): Likewise.
