QRegularExpression: refactor the handling of the study data
Consider the following situation:
- threads A and B have shallow copies of the same QRegularExpression
- threads A and B both call match() on a string
- thread A calls optimizePattern(), which doesn't optimize
- thread B calls optimizePattern(), which does optimize, and sets
studyData
- thread A uses studyData (set by B)
A needs to properly acquire the memory pointed by studyData
(which, in turn, needs to be released by B). This commit implements that.
(Before, we used to return a copy of the current studyData from
optimizePattern(), so A didn't see that B optimized the pattern
and set studyData).
