that GCC and Clang will support:
N3323 contextual conversion tweaks
N3653 member initialisers and aggregates
N3664 clarifying memory allocation
Of those, only N3653 brings a new syntax, so it could be added later.

Our inverse premultiply is rather unoptimized. It's major weakness is
using three divide operation which are the slowest integer operations.
This patch reduces the three divisions to just one but using an
approximation that is accurate for all uchar values.
The patch also adds a general short-cut for alpha==255.
Together these improvements makes it 2 to 16 times faster depending on
how many 0 and 255 alpha values are encountered.

...unless the user passed the -no-sse2 option to the compiler.
[ChangeLog][Important Behavior Changes] Qt now automatically generates
code for processors supporting SSE2 on i386 platforms. To disable
this, pass the -no-sse2 option during Qt configuration. Since this
feature has been present on CPUs for 10 years and since Qt no longer
checks for runtime support for SSE2, we strongly encourage users to
leave the default setting on for best performance.
- For Linux distributions that must retain support for CPUs without
SSE2, we recommend doing two builds of Qt and installing the
SSE2-enabled libraries in the LIBDIR/sse2 directory. Tools,
plugins, and examples are not affected.

If the compiler supports SSE2, we'll use our SSE2-optimised code
unconditionally. Runtime detection is left for SSSE3 code.
The SSE2 codebase is big and thus a timebomb if an inline function
gets leaked out and run without runtime check. In reality, it's
extremely unlikely people running CPUs without SSE2 support are
running Qt 5 at this moment (they're either too old or too new,
e.g. Intel Quark).
The SSSE3 codebase is a lot more manageable.

Passing -no-xcb disables xcb and related configuration tests
completely so for example QT_NO_XRENDER is not defined. This results
in linker errors in glxconvenience with -no-xcb since the XRender
calls are compiled in without linking to the library.
The XRender, XInput and such tests are not strictly xcb related and
may be used from elsewhere, for example glxconvenience which has
nothing to do with xcb. Therefore these tests are moved in configure
so that they are run even when xcb is disabled.

This is a partial revert of 39e04b0222.
The original change moved the special make install target path logic
into the logic for the app template to make it possible to remove the
condition that excluded builds inside the Qt directory. This was
to make it possible to build examples in the Qt directory for Android
without moving them. However, this broke user library projects,
specifically when they were part of a subdirs project and should
have been automatically installed into the Android package. This
patch brings back the logic but only enables it for library projects,
meaning that the only examples inside Qt which cannot be built
correctly are library projects (which didn't work anyway).
