Remove all "old atomic" code from Qt

The new atomic code was introduced in Qt 5.0. The platforms that did not
get ported were announced as deprecated in Qt 5.2. The code is now
removed in Qt 5.3.

The status for the platform/compiler/OS combinations affected is:
 * Linux with GCC or Clang: still compiles on all platforms
   (via qatomic_cxx11.h or qatomic_gcc.h)
 * INTEGRITY with Green Hills compiler: no longer compiles
 * Solaris on UltraSPARC, with Sun Studio: no longer compiles
 * AIX on POWER5 or 6, with IBM Visual Age: no longer compiles
   (probably did not compile Qt 5.0 either)
 * VxWorks in kernel mode: no longer compiles

[ChangeLog][General] Support for the following platforms has been
removed, due to lack of interest in updating support: INTEGRITY,
VxWorks, Solaris on UltraSPARC (with the Sun Studio compiler suite), AIX
on POWER processors (with IBM Visual Age compiler suite).
