824cc94921 QRegularExpression: minor fix to captureIndexForName
Although passing a null pointer to pcre16_get_stringnumber for
the compiled pattern should simply make it error out, it's actually
an undocumented behaviour, so let's stay safe and add an explicit
check.

Tests for this codepath are added.

b543141992 QRegularExpression: improve JIT memory handling
PCRE's JIT uses by default 32K on the pcre_exec caller's stack. This
is fine for most situations, but in some cases (esp. patterns with
lot of recursion) more memory is required.

Therefore, if a match execution fails due to exhausting JIT memory,
we let PCRE allocate up to 512KB to be used for the JIT's stack.

The pointer to the allocated memory is put in thread local storage
(so it can be reused from the same thread, if needed, and automatically
goes away when the thread dies).

eb70933398 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).

6b78980593 QRegularExpression: fix autotest
Some minor fixes: obviously, a valid match always come from a
valid regular expression, but a valid regular expression can create
an invalid match (internal error during matching).

Also, testing an invalid iterator should silence the emitted
warnings.
