[Windows] Remove functions in intrin.h that are defined in Builtin.def.

[jlebar]

Summary

These duplicate declarations cause a problem for CUDA compiles on
Windows. All implicitly-defined functions are host+device, and this
applies to the declarations in Builtin.def. But then when we see the
declarations in intrin.h, they have no attributes, so are host-only
functions. This is an error.

(A better fix might be to make these builtins host-only, but that is a
much bigger change.)
