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".

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

V4 RegAlloc: simplify algorithm after introducing half open ranges.

Now that all ranges are half open, and temporaries are defined at the
end of the (defining) statement, the linear scan algorithm get simpler.
Specifically, when allocating a register for a temporary, the check if
the temporary is defined or used is not needed anymore.

Another simplification is the handling of phi-nodes. Previously they
shared the same statement number as the first "real" statement in a
basic-block, and special checks were needed to handle them. Those are
now gone too.

V4 RegAlloc: change life-time intervals from closed to half-open.

There are two changes in this patch, that go hand-in-hand. First, when
re-numbering the statements in order of occurrence in the scheduled
basic-blocks, the (new) position is not stored in the statement itself,
but in the LifeTimeIntervals class. This makes it possible to re-use
information gathered during SSA formation or optimization.

The re-numbering itself has also changed, resulting in some minor
changes to the life-time interval calculation. The new numbering
is described in LifeTimeIntervals::renumber(). The reason is to make it
easy for the register allocator and stack-slot allocator to distinguish
between definition of a temporary and its uses. Example:

  20: %3 = %2 + %1
  22: print(%3)

If the life-time of %2 or %1 ends at 20, then at the point that %3 gets
assigned, it can re-use the storage occupied by %1 or %2. Also, when
both %1 and %2 need to get a register assigned (because they were
spilled to the stack, for example), %3 should be allocated "after" both
%1 and %2. So, instead of having a closed interval of [20-22] for %3, we
want to use an open interval of (20-22]. To simulate the "open" part, the
life-time of %3 is set to [21-22]. So, all statements live on even
positions, and temporaries defined by a statement start at
statmentPosition + 1.
