Edward Welbourne 53ed635dbb Set CONFIG += benchmark in corelib's various benchmarks 
This leads to "make benchmark" actually running the benchmark, which
would be nice, I think. Purged various CONFIG += release or -= debug
lines from the same configurations; those surely only configure how
the test code is compiled, which is more or less pointless; it's the
code under test whose debug/release state matters, and I don't suppose
that's affected by the build config of the test code.

In the process, reduce diversity of the ordering of lines within these
*.pro files and purge some dangling space.

Tor Arne Vestbø c3bd5ffdc8 Don't wrap feature detection macros with QT_HAS_FOO() variants 
Using wrappers for these macros is problematic when for example passing the
-frewrite-includes flag to preprocess sources before shipping off to distcc
or Icecream. It will also start producing warnings when compilers implement
http://eel.is/c++draft/cpp.cond#7.sentence-2. See for example
https://reviews.llvm.org/D49091

Both https://clang.llvm.org/docs/LanguageExtensions.html and the SD-6 document at
https://isocpp.org/std/standing-documents/sd-6-sg10-feature-test-recommendations
recommend defining '__has_foo(x) 0' as a fallback for compilers without the
macros, so that's what we go for.

Marc Mutz 333b1e9229 QReadWriteLock: add a check for writeOnly, too 
Results on my machine:

  PASS   : tst_QReadWriteLock::writeOnly(QMutex)

  RESULT : tst_QReadWriteLock::writeOnly():std::mutex:
     3,697 msecs per iteration (total: 3,697, iterations: 1)
  PASS   : tst_QReadWriteLock::writeOnly(std::shared_mutex)
  RESULT : tst_QReadWriteLock::writeOnly():std::shared_mutex:
     5,727 msecs per iteration (total: 5,727, iterations: 1)
  PASS   : tst_QReadWriteLock::writeOnly(std::shared_timed_mutex)
  RESULT : tst_QReadWriteLock::writeOnly():std::shared_timed_mutex:
     5,921 msecs per iteration (total: 5,921, iterations: 1)

(the 'nothing' test of course doesn't work with writing, as writing to
the same QString from different threads is UB)
