wp_finish: avoid making a goal unprovable

See merge request iris/iris!593

Make the IPM documentation more useful

See merge request !589

- Separated out the simpler invocations of tactics from their full
  forms. In the process we now document what parts of a tactic are
  optional.
- Convey what the common and rare tactics are, for example that the
  argument to `iModIntro` is rarely needed.
- Use "destruct" to talk about invoking an intro pattern, rather than
  eliminate, to stay closer to Coq terminology and avoid this potentially
  confusing PL term.
- Added an overview of the "grammar entries" relevant to many tactics
  (ipat, selpat, spat, and pm_trm). Added links to those sections
  everywhere.

Make iDestruct consume wands when it's supposed to

See merge request iris/iris!591

Tej Chajed authored 4 years ago and Robbert Krebbers committed 4 years ago

`iDestruct ("H" with "HP")` where "H" is persistent is supposed to
consume "H" if it isn't a forall. Due to a bug in the tactic, this
behavior was never triggered and "H" was always left alone.
