`__SSE_MATH__` indicates that the compiler will emit SSE instructions for floating-point math (also supported by GCC).

This is the default behavior in Clang. We could adjust the compiler options in the configure script to enable it on GCC as well (or disable it in Clang) for consistency across compilers.
