V4: Generate function tables on 64bit windows
In order for global exception handlers to be called reliably, the runtime
needs to unwind through JIT-generated code. This can be facilitated by
installing a "function table" for each JITed function that specifies "use
the frame pointer".
Also make sure to generate a function table for JIT'ed regular
expressions. Those were forgotten also in the linux case.
Fixes: QTBUG-50061
