2ff3899d62 fix(library/compiler/llnf): missing case at push_proj_fn 
We were not pushing projections over scalar projections.

07aa990f22 fix(library/compiler/borrowed_annotation): ensure that exported functions do not take borrowed arguments 
In the future, we should automatically generate wrappers that make all
adjustments for us.

ac9e37ed86 feat(library/compiler/llnf): we postpone the simplification of 1-reachable and all-eq cases_on expressions 
Reason: the `cases_on`-expressions are used to guide
`insert_reset_reuse_fn`. The new `simp_cases` simplifier applies the
1-reachable and all-eq cases_on expression simplifications after
`insert_reset_reuse_fn` is executed.

2f218f7ec0 refactor(library/compiler/llnf): remove reset/reuse insertion from to_llnf_fn 
`to_llnf_fn` now produces an IR similar to the \lambda_pure in our paper.

fe1d17583c feat(library/compiler/emit_cpp): special support for (proj|inc)*;reset sequences 
We save inc/dec operations. It improved the performance of
`expr_const_folding.lean`. On my Linux desktop

78440919e8 feat(library/compiler/llnf): avoid unnecessary inc x and dec x instructions 
Example:
```
x = lean::box(0);
...
lean::inc(x);
...
lean::inc(x);
...
lean::dec(x);
...
```
In the example above, the `inc` and `dec` operations are unnecessary
since `x` is known to be a (boxed) scalar value. This commit fixes this.

ab45af5936 fix(library/compiler/csimp): avoid potential expensive reduction at csimp 
`whnf_core(e)` uses `whnf` to reduce the major premise of recursors and
projections, and `whnf` unfolds arbitrary definitions.
This commit adds a new option (`cheap`) to `whnf_core`. When
`whnf_core(e, true)` is used, the type checker will not unfolding
definitions when reducing the major premises.
