intrinsic's callsite. Variants of the intrinsic with non-void return
type also return a value according to calling convention.
-On PowerPC, note that the ``<target>`` must be the actual intended target of

-local because no adjustment or restoration of the TOC pointer (in register r2)
-will be performed.

Requesting zero patch point arguments is valid. In this case, all
variable operands are handled just like
