No conflicts during the rebase.

But we get 3 errors when compiling:

error[E0599]: no function or associated item named `bind` found for struct `Binder` in the current scope
  --> compiler/rustc_codegen_llvm/src/gotoc/monomorphize/collector.rs:38:33

    |                  ^^^^^^^^^^^^^^^^^ method not found in `&Session`

error: aborting due to 3 previous errors

Investigating now.

[adpaco]

The last ones are due to a rework on the limits, which are not an attribute of the session but of the Rust typing context directly. This commit and this commit showed what changes were needed.

[adpaco]

The first one is due to this commit that removes bind from Binder.

Candidate branch is main-153-2021-07-09 which can be found here. CI fails since the fixes have been submitted for review in #318

[adpaco]

#318 was merged and main-153-2021-07-09 is now the default branch.
