Not if there are several calls to it with different parameters,
which may be the case with link time optimization.  Also, this
is a general mechanism - imagine it being used not for an llvm
intrinsic but for a routine from a runtime library; then llvm
wouldn't know about the special properties of the function.  But
that's ok, it doesn't have to!

Ciao,
