Doesn't Intel's own documentation say these are in pmmintrin.h?  gcc has them there as well.

[X86] DAZ Macros Relocation

The DAZ feature introduces the denormal zero support for x86.
Currently the definitions are located under SSE3 header, however there are some SSE2 targets that support the feature as well.
