So, actually it is supported for i686 only if any of vector extension is specified. I'm not sure whether we want x87 support for these intrinsics or not. Probably we may wait when glibc has implementation of these functions to lower it as a libcall.
It seems that none of these intrinsics are currently implemented for non-x86_64 (with the x86 backend):
Error output [godbolt]:
Similar to https://github.com/llvm/llvm-project/issues/53353 which was for x86_64
