See https://gcc.gnu.org/bugzilla/show_bug.cgi?id=85236
This is apparently an Intel SVML (short vector math library) function,
not an intrinsic that expands to a single hardware instruction, and we
don't have support for SVML yet.  It is also not clear how to
implement that support, and where to implement it.
