We expect that the C++ library also supports C++11 when the compiler
says it does as well. When using clang with libstdc++, the library has
no C++11 support or headers, so we cannot use, for example, #include
<initializer_lists>.

Modify configure.exe to run some configure-time tests and check if
the SSE and AVX compiler features are supported.
The tests themselves required a bit of changes to compile with
MSVC. The include in sse4_2.cpp was wrong. And for whatever reason, it
didn't like the volatile variables, which GCC, Clang and ICC have been
happy with. This should produce no effect in compilation, though: even
dead code must be syntactically correct. We're not running the output.

This allows us to have different flags for the compilers for
supporting the same feature. For example, the official flag in GCC to
support AVX2 is -mavx2, but ICC does not support it (yet), requiring
-march=core-avx2 or -xCORE-AVX2. That flag, instead, enables support
for all the features that the "Core-AVX2" processor (codename Haswell)
will support. And clearly, the MSVC flags are different.

For some reference platforms and SDKs we will need to pass in

This change introduces the -device <name> and -device-option
<key=value> option. The key value pairs will be written to a
qdevice.pri and can be used by the qmake.conf of the device spec.
The reason to not save the key value pairs in qconfig.pri is
becase of the fact that the device spec loads the qdevice.pri
earlier than the qconfig.pri. qdevice.pri allows the mkspec
to set the compiler flags and qconfig.pri allows configure to
add to those compiler flags.

Set QT_ARCH and QT_HOST_ARCH qconfig.pri variables based on the compiler
target. This is done by running qmake (twice when cross-compiling) on
config.tests/arch/arch.pro, which preprocesses a file that contains all
knowns processors.
On Windows, configure.exe has never run any config.tests before, and
does not currently have a function to run a program and capture its
output. Use _popen() to accomplish this (as qmake does for its system()
function). This needs to be done after qmake is built, as does the
mkspecs/qconfig.pri generation. As a side effect, the configure steps
have been slightly re-ordered, but the overall result is the same. The
displayConfig() call is moved to just before generating Makefiles, so
that it can show the detected architecture(s).

Do not write Q_BYTE_ORDER to qconfig.h in the configures. Instead,
we #define Q_BYTE_ORDER in qprocessordetection.h, since many CPUs only

Q_BYTE_ORDER depending on how the preprocessor sets __BYTE_ORDER__,
__BIG_ENDIAN__, or __LITTLE_ENDIAN__ (instead of using a compile test
to do so).
For operating systems that only support a single byte order, we can
check for Q_OS_* in addition to the preprocessor macros above. This is
possible because qprocessordetection.h is included by qglobal.h after
Q_OS_* and Q_CC_* detection has been done. Do this for Windows CE,
which is always little- endian according to MSDN.
