Map the lifetime dependencies described in terms of the formal AST-level parameters to the correct parameter(s) in the lowered SIL function type. There can be 0, 1, or many SIL parameters per formal parameter because of tuple exploding. Also, record which dependencies are on addressable parameters (meaning that the dependency includes not only the value of the parameter, but its specific memory location).
