Richard Henderson Sept. 9, 2020, 12:16 a.m. UTC 
Begin conversion of constraints to pre-validated, read-only entities.
To begin, create a simple method by which sets of TCGTargetOpDef
structures may be declared and used.  This simplifies each host's
tcg_target_op_def function and ensures that we have a collected
set of constraints.
