Fixes #269.

Make `big_op{L,M}_gen_proper_2` stronger

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

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.
