If include_nonconstraining is false, returns the list of parameters that are constrained by t - i.e., the value of each parameter in the list is uniquely determined by t (see RFC 447). If it is true, return the list of parameters whose values are needed in order to constrain ty - these differ, with the latter being a superset, in the presence of projections.

Returns the set of parameters constrained by the impl header.

Order the predicates in predicates such that each parameter is constrained before it is used, if that is possible, and add the parameters so constrained to input_parameters. For example, imagine the following impl:

Module rustc_typeck::constrained_generic_params
