3d79f89f5e fix(emacs/lean-mode): lean-execute
shell-quote-argument also escapes '~' into '\~' which causes a problem.
This fix first calls 'f-full' to get a absolute path, then call
shell-quote-argument.

2bc13f6bfd feat(library/tactic/exact): enforce goal type during elaboration when executing 'exact' tactic

enforce the goal type.

8295ef4e57 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.

11aad4449b feat(frontends/lean): add '[semireducible]' attribute
This commit also renames the elements of reducible_status.
The idea is to use in the C++ implementation the same names used in the
Lean front-end.

7e2f0f9a36 fix(library/unifier): in the context_check, we should not consider local constants that occur in the type of other constants
This was a performance bug.
We were missing higher-order pattern constraints due to this bug.
