I think the background is that for some targets there is a special instruction for this purpose. Gcc has special support for a RTL instruction pattern that is then matched to a built-in function. The test cases seem to be useful for testing this feature.
As a side note, I find it odd that the GCC test suite would require such a non-ANSI standard function to be in the libc. But yeah, it's easy enough to add.
