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'.
See issue #500

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