Following up on using GCC's autovectorizing for faster SSE4.1
premultiply, this patch adds specialized autovectorized versions
of premultiply for AVX2, giving another almost doubling in speed.
To make the speed up for AVX2 and also SSE4_1 available to non-GCC
compilers, the target-specific methods have been moved to separate
files.

setDevicePixelRatio is often called unconditionally even when the
devicePixelRatio matches the pixmap or image.
This causes a lot of unncessary detaches wasting some memory.

It was preventing some functions in the Qt namespace
from being documented and hence auto-links to these

Moved to processKeyEvents() on all platforms except OS X.
Previously QWindowSystemInterface::tryHandleShortcutEvent() was called
from inside QWindowSystemInterface, this is considered unsafe as it
ends up calling sendEvent(). On some platforms the call might come from
a different thread then the receiver and cause an assert.

Currently Qt uses the QPlatformIntegration::StyleHint
SynthesizeMouseFromTouchEvents to check whether to synthesize mouse
events from touch events. But not only platform plugins can produce
touch events, they can be created by e.g. QTest::touchEvent() and in
this case we almost definitely need synthesizing regardless of the
platform.
This commit introduces a QTouchDevice::MouseEmulation capability which
replaces use of the QPlatformIntegration::SynthesizeMouseFromTouchEvents.
So it's possible to pass QTouchDevice without this capability to
QTest::touchEvent() and be sure that mouse events will be synthesized.
Notice that touch pads always emulate mouse events.
As a result we can activate some tests which were disabled for specific
platform configurations by commits 6c1670d8c273819435867c42725c0db0eee597dc
and e9760f1559361c39f269fb89f1ebd01f6ee8378d.

The current attempt to fix the problem described in b8d0fac5a9
has shown to have unforeseen issues. The assert in the
patch has been triggered in user code (see bug report), which, when
looking more closely, shows that the assert cannot be guaranteed
for all cases. E.g if user code (or Qt drag'n'drop code) starts a new
event loop upon receiving the move event, this can deliver new mouse
events before the move returns, which will trigger the assert.
So it seems like the most correct solution is to *post* the second button
event after all (directly trailing the move event), to at least make sure
mouse events are being delivered in the correct order. The crash that caused
the original change will need to be fixed by other means.

Change c238d34137ffe80d30933733a12aa2893b9631c2 was a refactoring
which slightly changed behavior. In the case of fetching the
alpha map's bounding box, before we would call loadGlyph()
even for the case of outline drawing, as the correct bounding
rect is still needed for this case. In loadGlyphFor() however,
0 was always returned for this case, as it was only used for
populating the cache.
The simple fix for this is to add a bool to loadGlyphFor() which
adapts the original behavior when set, similar to the
fetchMetricsOnly bool in the loadGlyph() functions.
