sljit, the JIT in pcre2, doesn't quite fully work on windows on
arm yet (although the subset of functionality used by pcre2 might
mostly work). On arm64, it fails to compile (although working around
that failure is pretty easy), when using clang in MinGW mode
(where __GNUC__ is defined, making the JIT auto-enabled).
Disable it in these configurations until it has been fully tested
and fixed upstream first.

Both iOS and tvOS need to have JIT disabled, so use the uikit qmake
scope for that. This was already done for PCRE 1, but the corresponding
change was lost for PCRE 2 (probably due to a bad merge).

pcre2_printint.c does not need to be compliled as a standalone source
file, as it's #included from pcre2_compile.c. Apparently qmake does not
detect this in all cases, and sometimes tries to compile pcre2_printint.c,
resulting in compile errors.

PCRE1 is going towards EOL. PCRE2 is the way forward in terms
of new features, performance, and security improvements. The
APIs that QRegularExpression uses are similar so the required
modifications aren't extensive.
The biggest difference comes to JIT-compiling of the pattern.
In PCRE1, JIT-compiling did not modify the processed PCRE pattern,
but returned a new chunk of data.
This allowed multiple threads to keep matching using the same
processed data and NULL for the JIT data, until a thread
JIT-compiled and atomically set the shared JIT data to the results
of the compilation.
In PCRE2, JIT-compiling _modifies_ the processed PCRE pattern in a
way that it's thread unsafe [1]; the results of JIT-compilation
are stored somewhere inside the processed pattern.
This means the above approach cannot work -- a thread may be
matching while another one JIT-compiles, causing a data race.
While waiting for better workarounds from upstream, employ a
read/write mutex to protect the matching from JIT-compilation.

[ChangeLog][General] QRegularExpression now requires the PCRE2
library, at least version 10.20. Support for the PCRE1 library
has been dropped. A copy of PCRE2 is shipped with Qt and will
automatically be used on those platforms which lack it.
