Disable PCRE JIT on iOS

First of all, we were missing an implementation of SLJIT_CACHE_FLUSH,
as ___clear_cache was not available and we would get missing symbols.

This was fixed in upstream PCRE 8.31, but even then the JIT would
only work on jailbroken devices, so we disable it.

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).
