Added memory space parameters support at the autogeneration script.

Added memory space parameters support at the autogeneration script.

Enhance the python script to support pointer with memory space
type, such as :

gentype fract (gentype x, __global gentype *iptr)
gentype fract (gentype x, __local gentype *iptr)
gentype fract (gentype x, __private gentype *iptr)

So enable the following function at the builtin function spec file
fract/frexp/modf/nextafter/remquo/sincos.

Remove the duplicate at the ocl_stdlib.tmp.h.
