Tidied up the existing float tests in the process.
(In particular, s/SUCCESS/PASS/ since that matches real test output.)
These verify that QCOMPARE() handles floats and doubles as intended.
Extended the existing qFuzzyCompare tests to probe the boundaries of
the ranges of values of both types, in the process.
Revised the toString<double> that qCompare() uses to give enough
precision to actually show some of the differences being tested there
(12 digits, to match what qFuzzyCompare tests, so as to show different
values rather than, e.g. 1e12 for both expected and actual) and to
give consistent results for infinities and NaN (MinGW had eccentric
versions for these, leading to different output from tests, which thus
failed); did the latter also for toString<float> and fixed stray zeros
in MinGW's exponents (which made a kludge in tst_selftest.cpp
redundant, so I removed that, too).
That's further complicated handling of floating-point types, so let's
just keep an eye on how expensive that's getting by adding a benchmark
test for QTest::toString(). Unfortunately, default settings only get
runs that take modest numbers of milliseconds (some as low as 40)
while increasing this with -minumumvalue 100 or more gets the process
killed - and I'm unable to find out who's doing the killing (it's not
QProcess::kill, ::kill or the QtTest WatchDog, as far as I can tell).
So results are rather noisy; the integral tests exhibit speed-ups by
factors up to 5, and slow-downs by factors up to 100, between runs
with and without this change, which does not affec the integral tests.
The relatively modest slow-downs and speed-ups in the floating point
tests thus seem likely to be happenstance rather than signal.

In selftests.qrc, imposed alphabetic order (on stem of name, then on
suffix, effectively treating . as sorting before any letter) while
removing old tests and adding new tests and data. Updated all non-csv
files and added many missing files. (Not clear on csv support status;
the script seems to have dropped it after 5.6, but the test still uses
it.)
Left expected_crashes* alone (no new files added, no update to old) as
I don't get results resembling those anticipated.
Omitted printdatatagswithglobaltags, printdatatags due to dangling
hspace on output lines, which upset sanity-bot. A change to the test
cpp is needed to make it viable to skip that dangling hspace.

Some of the subtests are only run with plain-text output format. For
those subtests, the other output formats were unused and gradually
becoming out-of-date.

This test was attempting to verify two completely unrelated things, so
this commit splits it into two tests.
Also, printf calls are replaced by qDebug so that the test does not
bypass the testlib loggers.
