// Test to make sure that inner functions within a polymorphic outer function

|
// don't get re-codegened when the outer function is monomorphized. The test
|
|
// code monomorphizes the outer functions several times, but the magic constants
|
|
// used in the inner functions should each appear only once in the generated IR.
