Here is a patch so that bench-memcpy-random.c prints out timings for
all the IFUNC versions of memcpy. Â The TEST_NAME change is clear,
TEST_NAME isn't really the name of the test but the name of the routine
being tested. Â If you call it memcpy-random it looks for IFUNC versions
of the memcpy-random function instead of the memcpy function. Â I also
changed the IMPL call to have 1 instead of 0 as the second argument. Â I
don't really understand this change, but it is what the other two
memcpy tests do so I copied them and it seems to work. Â Tested on x86
and aarch64.
