Remove -arch argument and #define QT_ARCH from configures Do not try to detect the host or target architectures using uname or similar, and do not override with the -arch or -host-arch configure arguments. The configures will still accept the -arch and -host-arch arguments, but it ignores them and instead outputs a warning stating that these arguments are obsolete and should not be used. 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).

Ensure that qXXXdetection.h can be included directly Those files might have dependency on one another, on qconfig.h and on early qglobal.h definitions, so ensure that the only correct include order is that of qglobal.h.

Add QSysInfo::cpuArchitecture() and fullCpuArchitecture() This uses the same logic as the config.test, so we will return the same string as the $$QT_ARCH variable in qmake for cpuArchitecture(). fullCpuArchitecture() is meant to be used in upgrade mechanisms, when combined with the OS type.

qsimd: add support for new x86 CPU features This adds detection for: VAES, GFNI, AVX512VBMI2, AVX512VNNI, AVX512BITALG, AVX512VPOPCNTDQ, AVX512_4NNIW, AVX512_4FMAPS. These features were found in the "Intel® Architecture Instruction Set Extensions and Future Features" manual, revision 30. This commit also adds support for RDPID (already in the main manual) and the Control-flow Enforcement Technology, which appears in a separate Intel paper. This new support was done by adding a new generator script so we don't have to maintain two tables in sync, one in qsimd.cpp with the feature names, and the other in qsimd_p.h. Since we now need a lot more bits, it's no longer worth keeping the two halves of the qt_cpu_features variable mostly similar to the main two CPUID results. This commit goes back to keeping things in order, like we used to prior to commit 6a8251a89b6a61258498f4af1ba7b3d5b7f7096c (Qt 5.6) At the time of this commit, GCC 8 has macros for AVX512VPOPCNTDQ, AVX512_4NNIW, AVX512_4FMAPS, AVX512VBMI2 and GFNI.

qsimd: add support for new x86 CPU features This adds detection for: VAES, GFNI, AVX512VBMI2, AVX512VNNI, AVX512BITALG, AVX512VPOPCNTDQ, AVX512_4NNIW, AVX512_4FMAPS. These features were found in the "Intel® Architecture Instruction Set Extensions and Future Features" manual, revision 30. This commit also adds support for RDPID (already in the main manual) and the Control-flow Enforcement Technology, which appears in a separate Intel paper. This new support was done by adding a new generator script so we don't have to maintain two tables in sync, one in qsimd.cpp with the feature names, and the other in qsimd_p.h. Since we now need a lot more bits, it's no longer worth keeping the two halves of the qt_cpu_features variable mostly similar to the main two CPUID results. This commit goes back to keeping things in order, like we used to prior to commit 6a8251a89b6a61258498f4af1ba7b3d5b7f7096c (Qt 5.6) At the time of this commit, GCC 8 has macros for AVX512VPOPCNTDQ, AVX512_4NNIW, AVX512_4FMAPS, AVX512VBMI2 and GFNI.

Record the sub-architecture (CPU features enabled in the compiler) If the system's compiler has extra features on top of the base settings enabled or if the mkspec or $CXXFLAGS variable included some, record them. This will allow us to choose whether or not to use our own special compilers, based on whether the system default compiler contains it or not.

Make build ABI available as qmake variable This is needed to encode the correct ABI into the generated qml caches. It is identical with the return value of QSysInfo::buildAbi().

Improve the architecture-detection mechanism For the Unix part, this now obeys the -v option, printing the full command-line it used to compile, allowing testers to identify why something went wrong. Unfortunately, it requires a full compilation cycle, instead of just preprocessing. Just one more among the many on Unix, but maybe a noticeable slow-down on Windows.
