Remove usages of QT_ARCH and QT_ARCH_* from qtbase

The architecture is detected at compile time based on the predefined
macros from the compiler. Don't use QT_ARCH in .pro, .pri, or .prf
files.  The PNG_NO_ASSEMBLER_CODE define from libpng.pri is not present
in the current copy of src/3rdparty/libpng, so no change in
functionality is expected.

The conditional for the SUPPORT_JIT define in pcre.pri is moved to
src/3rdparty/pcre/config.h, again so that we can use the compiler's
predefined macros to detect the architecture at compile time.

Replace QT_ARCH_ARM, QT_ARCH_MIPS, and QT_ARCH_SPARC with their
Q_PROCESSOR_* equivalents.

Replace QT_ARCH_INTEGRITY, QT_ARCH_VXWORKS, and QT_ARCH_WINDOWSCE with
their Q_OS_* equivalents.

Note that this commit also effectively disables the SPARC atomic
implementation. An inline implementation for SPARC needs to be added,
or we remove the current code and instead rely on the GCC intrinsic or
C++11 std::atomic support on SPARC.

Note also that this commit does not remove QT_ARCH from configure or
qconfig.h. This will continue to be set until all Qt 5 projects can be
moved away from using QT_ARCH.
