Yes it will conflict.

Atomic doubles are not guarded properly for other builtins (outside of the `cl_ext_float_atomics` extensions) either, and I have a different solution in mind to solve it for all uses and extensions.  So we could leave out the .td changes from this patch and only merge the `opencl-c.h` changes.
