The name of the builtin may be misleading, but changing semantics of a
builtin after it has been in use for 9 years is even worse.  The origin
of the builtin is in ia64intrin.h and therefore icc, I guess, so
it matters what icc is implementing.  H.J., could you please check out what
this intrinsics does with icc on ia64?
