info.initial_parms instead of info.orig_decl.
(normalize_constraint_expression): Take a norm_info object
instead of a bool. Cache the result of normalization.
(tsubst_nested_requirement): Call satisfy_constraint_expression
instead of satisfy_constraint, so that we normalize on demand.
(satisfy_constraint_expression): Handle a NESTED_REQ argument.
Adjust call to normalize_constraint_expression.
(finish_nested_requirement): Set the TREE_TYPE of the NESTED_REQ
