Add the patch I added to qt4-corelib in r317896 to some other Qt ports.

These ports which previously failed to build with clang-i386 use their
private copies of the qsimd_p.h header, since this private header is not
installed at all (which, in turns, makes the PORTREVISION bump in
qt4-corelib quite useless).

We thus need to add a copy of the same patch to all these ports to make sure
the qsim_p.h they use when being built is actually the one we want.

Hopefully this gets miwi happy and people on clang-i386 can build these
ports again.

+    Check that 3DNow! instructions are supported before including mm3dnow.h.
+    
+    Include mm3dnow.h the way we already include the (S)SSE{3,4} and AVX
+    instruction headers: by checking that the compiler is set to support those
+    instructions besides verifying that QT_HAVE_3DNOW evalues to true (which
+    only means the compiler supported them when the build was being configured).
+    
+    This has not caused a problem in most cases so far because GCC protects its
+    mm3dnow.h header with an #ifdef __3dNOW__ (contrary to what it does on, say,
+    pmmintrin.h). clang's mm3dnow.h, on the other hand, does not have that check
+    and can fail if -march is set to, for example, i386 or i486.
+    
+    Not backported from qt5 because qtbase because qsimd_p.h does not include
+    the 3DNow! headers after commit a1b30b49ef09bef2e97b9a0622bf7ad622678fee.
