I created and used the _CLC_V_V_VP_VECTORIZE in first iteration of
series to implement modf builtin based on the AMD builtin library.
However in the second try I used much simpler approach based on the
reference implementation that no longer used the macro. So I guess it
was probably pushed by accident. Feel free to fix it/use it anyway you
And yeah, I'm quite sure that the address space part was broken...
