V4 IR: (natural) loop detection.

We perform loop detection to be able to assign to each block its loop,
an chain them up from inner loop to outer loop. The new algorithm works
on each basic block just once, and looks at a basic block just the
number of connections it has. As it relies on the dominator tree it is
more robust on actually finding al looping constructs and only those
rather than relying on the statements used. It assumes that a basic
block is analyzed before the one that dominate it (to guarantee finding
outer loop headers before inner loop headers), so blocks are ordered to
work on them in a way that guarantees that, using dominator tree depth,
that is trivially available.

Loop detection allows us to then schedule the loop body before the part
after the loop (the header dominates both so just domination cannot
choose between both), and can be used to optimize loops (either
unrolling the first iteration or hoisting constant parts out of it).

It also helps with generated JavaScript code: in order to simulate gotos
or other unconditional branches, nested labeled do-while(false) loops
are often used in combination with break/continue to "jump" between
"loops".

Avoid double deletion of QQuickWindow

It's uncertain why 4fc0df58b8458052a818e3e970a97457882808e6 added
the call to sendPostedEvents(0, QEvent::DeferredDelete) but now we can
see that it easily results in the destructor calling itself, and
therefore double-deleting its own d_ptr.  removePostedEvents seems
safer to ensure that the window cannot be doubly deleted, in spite
of the qdoc warning that "You should never need to call this function."

Fix intermittent crash with older MinGW releases

An alternate code-path was previously added to work around a bad
signature for the SHParseDisplayName() function in older and non-w64
versions of the MinGW headers. This code-path incorrectly passed a
single rather double indirect pointer to the third argument of that
function causing it to produce corrupt data and subsequently crash.
This change modifies the code to instead cast a pointer of the correct
type to the incorrect type expected by the headers.

Fix crash in QObjectWrapper

Use QSignalSpy instead of waitFor in tst_qpacketprotocol

QTcpServer::waitForNewConnection() blocks the event loop and prevents
the client, that runs in the same event loop, from sending anything.
Also, if the connection is established before waitForNewConnection() is
called we're going to wait for another connection, which will never
happen.

It's not clear if this is actually the cause of the test failures but
blocking the event loop is generally a bad idea and the last change to
the test that actually made a difference to the functionality added
exactly that line, see b36bbe3626bc68ac267d7653fa6408a8f258251d.

V4 JIT: add hint for phi-node operands.

Not only is it preferable for the target of a phi-node to be stored in
the same location as one of the sources, but the same yields for the
sources. For example, in a loop, it is preferable to store the result
of a value used in a phi-node in the loop header to be stored in the
same location as that phi-node's target. Doing that will eliminate extra
moves that are generated to resolve differences between edges.
