Don't compile crc32c-intel on non-x86 platforms
crc32c_intel() doesn't make sense on platforms without SSE, so alias it
to crc32c() on such machines.

Add ramp_time option
Sometimes it's useful to let a job settle for a little while
before taking any measurements on latency and throughput, since
the initial rate on eg a write workload may be much higher than
the longer sustained rate.
So add a ramp_time option that allows the user to specify a lead
ramp time that must have passed before fio takes any performance
numbers into account.

filehash: check for NULL ->file_name in hash lookup
Original patch from Shaozhi Shawn Ye <yeshao@google.com>, modified
by me to continue the lookup and just skip the file instead of
returning NULL.
