Add check for invariant TSC on x86 and use TSC is default clock if reliable
TSC is by far the fastest clock we can use. Check the CPUID bits for
whether it is both constant rate AND synced across cores. If it is,
we can use it as our default clock source.
Fio will default to this clock source on x86 if no other clock source
is specifically given with clocksource= in the job file.

Auto-detect whether to use hw assisted crc32c
Little point in separating the two. If the hardware assisted
crypto is available, always use it.

A few fixes for 32-bit compiles
- Change the HAVE_SSE to HAVE_SSE4_2 and only provide it on
x86-64.
- Cast two values that otherwise cause the compiler to warn on 32-bit

crc32c-intel: replace SIGILL approach with cpuid
Some operating systems log illegal instructions, lets try and
be a bit nicer and use cpuid to identify the presence of
SSE4.2 which is needed to support the hw crc32c instruction.

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.
