refactor(library): replace 'calc_trans', 'calc_symm', 'calc_refl' and 'calc_subst' commands with attributes '[symm]', '[refl]', '[trans]' and '[subst]'
...
These attributes are used by the calc command.
They will also be used by tactics such as 'reflexivity', 'symmetry' and
'transitivity'.

fix(library/tactic/class_instance_synth): constraint execution order at type class resolution
...
We could not fix this problem before because we did not have the

Without this annotation, the fixed TC would loop in some HoTT files.
