fio: fix cycles_start build issue
There is an issue introduced with "commit 73df3e07 gettime: offset CPU cycle
counter by initial value". For architectures which define
ARCH_CPU_CLOCK_CYCLES_PER_USEC (currently only s390) this causes a build
error
gettime.c:174:11: error: ‘cycles_start’ undeclared (first use in this
function)
if (t < cycles_start && !cycles_wrap)
To make sure variables and code are only compiled in the same cases I
added a
clock definition called ARCH_CPU_CLOCK_WRAPS. We could merge
ARCH_CPU_CLOCK_WRAPS and the existing ARCH_CPU_CLOCK_CYCLES_PER_USEC
into one
if you prefer, so far nobody else uses it.
To avoid cluttering all architecture headers I enabled it by default in
arch-generic.h, so any arch not needing the wrap handling can undef
ARCH_CPU_CLOCK_WRAPS later in their headers.

fio: fix s390 timing for older machines/binutils
Older gcc/binutils or one with very low default march will refuse to use stckf.
On top of that machines older than a z196 don not even have the store clock
fast facility.
To fix all of those issues, check for the facilities in configure step and make
the usage of stckf and a matching march dependent to it.

fio: fix s390 nop
When trying to run rate limited fio runs we encountered that the current
definition of a nop uses a privileged instruction which is not even a nop,
but a yield call to the hipervisor.
That leads to a SIGILL as it is privileged.
To solve that issue replace it with a nop, the assembler will take care
of it (likely to become a BCR 0,0)

fio: fix s390 time accounting
The current timer implementation could cause time warps on s390 which ends up
as time bound jobs that would never end, because they always reset themself to
the old time.
When touching this code anyway, we also change it to use the faster stckf
and avoid the calibration as we can control the result to be usecs.
This also eliminates a few calculations cycle->usec in the hot path for the
timer.
In case other architectures have similar improved timers that might not be
usec based, but nsec based or such a thing any architecture can set
ARCH_CPU_CLOCK_CYCLES_PER_USEC to an appropriate per-arch value.
This leaves the infrastructure open for others and the compiler will throw
our division by 1 away anyway.

Rename ffz() function to fio_ffz() to avoid conflicts
Newer gcc/glibc include an ffz function. Lets just do the easy
thing and rename ours to fio_ffz(), then we can look into reusing
a provided one later if necessary.
