QRegularExpression: add optimizations autotest

Exporting the counter that controls the optimization of a compiled
pattern lets us to forcibly optimize all patterns. Therefore,
two tests are now run: one with default optimization values
and another one which always optimizes the pattern.

The counter itself was renamed with a qt_ prefix and put
inside the Qt compilation namespace
(thanks to rohanpm for pointing it out).
