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.

It was probably part of the original design to have an intermediate
measurement to determine whether the results were acceptable or not, but
it was never used. So just remove.

As if QIODevice::readLine() and QIODevice::Text open-mode aren't slow
enough, the old code took the line QByteArray, converted it to a
QString so it could apply a trivial regex to it: '^summary: (\d+)'.
We can, of course, use QByteArray::startsWith("summary: ") followed by
std::from_chars(), these days, to get the same effect, without having
to JIT-compile an RX and convert every line into UTF-16 first.

In one case, I took the liberty to remove a useless

don't use Q_FOREACH anymore, we don't incur the copy
