Tell the compiler that next() and isDone() cannot throw, so it doesn't
need to create exception handling code. This might yield more faithful
benchmark results for micro-benchmarks.
As a drive-by, mark isDone() as const, too.

And pass the value in a qreal, which is what QBenchlib stores
anyway. This increases the code size a little because the conversion
from integer to qreal is in multiple places, but doesn't meaningfully
increase the overhead: in the SysV ABI, we still return Measurement in
registers and even using the floating point registers where applicable.
This is the first step in allowing the Perf benchmarker to benchmark more
than one event.

You can create multiple instances of QBenchmarkGlobalData as the ctor
is public.
The qmltest plugin does create a static one, but only conditionally
assigns it to the singleton pointer. On shutdown the plugin is removed
and the QBenchmarkGlobalData::current should only be reset by the dtor
if it's actually pointing to the same object.

supported, drop some unused includes, and fix some tests that were

QBenchmarkTimeMeasurer uses the 3rd party header cycle_p.h which may
include windows.h on Windows (32bit). This can cause clashes in qmltest,
which uses QBenchmarkMeasurerBase. Move the derived classes to a separate
header to prevent this.

Short-lived benchmarks (benchmarks that complete in a very short period
of measured time) are often more affected by jitter and warm-up effects
than longer running benchmarks. Since QBENCHMARK stores the median
result of all accepted benchmark runs, a larger number of aggregation
runs is preferable for short-lived tests, but not necessarily for longer
running ones. The minimumtotal option, specified in units of the
selected measurement, will make the benchmark repeat a benchmark until
the total measured cost exceeds the specified threshold. The displayed
median result will then tend to be more accurate. This is especially
useful for data-driven benchmarks in case the data tags scale the
benchmarked operation from little to large cost.
