-; This test checks that we propagate the functions through arguments and attach
-; !callees metadata to the call. Such metadata can enable optimizations of this
-; code sequence.
-;
-; For example, the code below a illustrates a contrived sort-like algorithm
-; that accepts a pointer to a comparison function. Since the indirect call to
-; the comparison function has only two targets, the call can be promoted to two
-; direct calls using an if-then-else. The loop can then be unswitched and the
-; called functions inlined. This essentially produces two loops, once
-; specialized for each comparison.
