This avoids recompilation of coq_tactics each time an instance is added.

The new implementation ensures that type class arguments are only infered in the very end. This avoids the need for the inG hack in a0348d7c.

This reverts commit c43eb936. The hack using class_apply has some strange behaviors, see: https://sympa.inria.fr/sympa/arc/coqclub/201607/msg00094.html

The intropattern {H} also meant clear (both in ssreflect, and the logic part of the introduction pattern).

For example iIntros "{$H1 H2} H1" frames H1, clears H2, and introduces H1.

This fixes a bug in 916ff44a causing proof mode notations not being pretty printed.

This tweak allows us to declare pvs as an instance of FromPure (it is not an instance of IntoPure), making some tactics (like iPureIntro and done) work with pvs too.

We are now using the prefixes Into, From, and Is (the first two are inspired by the names of some traits in the Rust stdlib), and hopefully doing that consistenly.

Generating a fresh name consists of two stages: + Use [cbv] to compute a list representing the domain of the environment. This is a very simply computation that just erases the hypotheses. + Use [vm_compute] to compute a fresh name based on the list representing the domain. The domain itself should never contain evars, so [vm_compute] will do the job.

To do so, we have introduced the specialization patterns: =>[H1 .. Hn] and =>[H1 .. Hn] That generate a goal in which the view shift is preserved. These specialization patterns can also be used for e.g. iApply. Note that this machinery is not tied to primitive view shifts, and works for various kinds of goal (as captured by the ToAssert type class, which describes how to transform the asserted goal based on the main goal). TODO: change the name of these specialization patterns to reflect this generality.

Changes:  We no longer have a different syntax for specializing a term H : P ★ Q whose range P or domain Q is persistent. There is just one syntax, and the system automatically determines whether either P or Q is persistent.  While specializing a term, always modalities are automatically stripped. This gets rid of the specialization pattern !.  Make the syntax of specialization patterns more consistent. The syntax for generating a goal is [goal_spec] where goal_spec is one of the following: H1 .. Hn : generate a goal using hypotheses H1 .. Hn H1 .. Hn : generate a goal using all hypotheses but H1 .. Hn # : generate a goal for the premise in which all hypotheses can be used. This is only allowed when specializing H : P ★ Q where either P or Q is persistent. % : generate a goal for a pure premise.

We may want to do the same for iIntros ? and iDestruct "H" as {?} "H", but that requires more work. However, I do not think I want to rely on names chosen this way.

iSpecialize and iDestruct. These tactics now all take an iTrm, which is a tuple consisting of a.) a lemma or name of a hypotheses b.) arguments to instantiate c.) a specialization pattern.

These tactics are superfluous:  iPure H as pat => iDestruct H as pat  iPersistent H => iSpecialize H "!"
