This PR removes uses of `Lean.RBMap` in Lean itself.
Furthermore some massaging of the import graph is done in order to avoid
having `Std.Data.TreeMap.AdditionalOperations` (which is quite
expensive) be the critical path for a large chunk of Lean. In particular
we can build `Lean.Meta.Simp` and `Lean.Meta.Grind` without it thanks to
these changes.
We did previously not conduct this change as `Std.TreeMap` was not
outperforming `Lean.RBMap` yet, however this has changed with the new
code generator.
This PR modifies the encoding from `Nat` to `Int` used in `grind
cutsat`. It is simpler, more extensible, and similar to the generic
`ToInt`. After update stage0, we will be able to delete the leftovers.
This PR extends the `Eq` simproc used in `grind`. It covers more cases
now. It also adds 3 reducible declarations to the list of declarations
to unfold.
This PR implements `exists` normalization using a simproc instead of
rewriting rules in grind. This is the first part of the PR, after update
stage0, we must remove the normalization theorems.
This PR implements `forall` normalization using a simproc instead of
rewriting rules in `grind`. This is the first part of the PR, after
update stage0, we must remove the normalization theorems.
This PR fixes stealing of `⇓` syntax by the new notation for total
postconditions by demoting it to non-builtin syntax and scoping it to
`Std.Do`.

This PR tries to improve the E-matching pattern inference for `grind`.
That said, we still need better tools for annotating and maintaining
`grind` annotations in libraries.
closes#9125
This PR fixes the syntax of `grind` modifiers to use `patternIgnore` for
cases where both unicode and ascii variants are matched. This fixes an
issue where several variants of grind syntax weren't accepted (e.g.
`@[grind ← gen]`). Additionally, this reduces the chance that we get
another syntax matching bootstrap hell.
This PR corrects the pretty printing of `grind` modifiers. Previously
`@[grind →]` was being pretty printed as `@[grind→ ]` (Space on the
right of the symbol, rather than left.) This fixes the pretty printing
of attributes, and preserves the presence of spaces after the symbol in
the output of `grind?`.
