Remove some obsolete declarations

Ensure that cmStandardIncludes.h is included before any platform header
in cmGeneratorExpressionEvaluator.h.  That file needs to change as
a result of removal of the cmMakefile.h header from
cmGeneratorExpressionNode.h, affecting the compilation of
cmGeneratorExpressionNode.cxx.

On AIX we need to include our own headers first to get large file
support macros defined consistently within system headers.  The old
order in this header worked only because it was always included after
other headers.
