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.

Robin Burchell 442eee3cda QStack: Add a simple benchmark.
This covers the only real additions over QVector: push and pop. Really, there
isn't too much specific to benchmark here, but we're interested in one specific
case: that of pushing and popping a single item repeatedly.

With the current QVector behavior, this causes constant deallocation, which
makes it morbidly slow. This behavior will be reviewed in a subsequent commit.

Results (not that anyone really cares) for me:
    PASS   : tst_QStack::qstack_push()
    RESULT : tst_QStack::qstack_push():
         1.9 msecs per iteration (total: 61, iterations: 32)
    PASS   : tst_QStack::qstack_pop()
    RESULT : tst_QStack::qstack_pop():
         8.2 msecs per iteration (total: 66, iterations: 8)
    PASS   : tst_QStack::qstack_pushpopone()
    RESULT : tst_QStack::qstack_pushpopone():
         80 msecs per iteration (total: 80, iterations: 1)
