heap_lang/lifting.v: Don't run auto on hopeless goals

See merge request iris/iris!369

Paolo G. Giarrusso authored 5 years ago and Robbert Krebbers committed 5 years ago

Those goals happen to be solvable by [done] as well, so use that.

I also dropped some inconsistent line breaks.

Added variant of big_sepL_lookup_acc which allows updating the value

Coq master is stricter about checking for meaningless implicit binders;

Better handling of persistent results in `iDestruct`, `iPoseProof`, `iAssert` and friends

See merge request iris/iris!341

Make handling of `AddModal` in `tac_specialize_frame` consistent with that in `tac_specialize_assert`.

The result of `iSpecialize ("H" with "[H1 .. Hn]")` was always put in the
spatial context. This commit strenghtens this tactic by putting the result
in the intuitionistic context if the following conditions hold:

1. The hypothesis `H` is persistent.
2. All the hypotheses `H1 .. Hn` are intuitionistic (or similarly, in case
   `[-H1 .. Hn]` is used, if all remaining hypotheses are intuitionistic).
3. If the pattern `[> ..]` for adding a modality is not used.

This version allows to relate structures over different types.

This way, it is possible to use them inside the section for
different types of maps at the same time.

Add several lemmas about list singletons

See merge request iris/iris!364

A lemma that allows to relate a singleton with another list.

Add a stronger version of `list_core_id`.

See merge request iris/iris!361

Add pair_op_1 and pair_op_2

See merge request iris/iris!362

`list_lookup_singletonM_ne` is not sufficient when we need to
compare a singleton with another list, for example, to see if one
is included in the other.

A new lemma, `list_core_id'`, allows to infer that a list is
`CoreId` by only checking that all its elements are `CoreId`, as
opposed to the existing instance, `list_core_id`, that only works
when the list contains elements of the type where every element is
`CoreId`.

The two new lemmas allow splitting the resources in one component
of a pair when the other component has nothing. In combination
with `pair_split`, they allow to arbitrarily split the resource
`(a ⋅ a', b ⋅ b')`.

This is in line with `prod_local_update_1` and
`prod_local_update_2`, the lemmas that allow, in a sense, to only
consider one component of a pair.
