a0fc455d30 Replace absolute paths with relative ones 
Modern compilers allow reaching external crates
like std or core via relative paths in modules
outside of lib.rs and main.rs.

e72e43c730 Replace (Body, DefId) with Body where possible 
A `Body` now contains its `MirSource`, which in turn contains the
`DefId` of the item associated with the `Body`.

88197214b8 Auto merge of #75573 - Aaron1011:feature/const-mutation-lint, r=oli-obk 
Add CONST_ITEM_MUTATION lint

Fixes #74053
Fixes #55721

This PR adds a new lint `CONST_ITEM_MUTATION`.
Given an item `const FOO: SomeType = ..`, this lint fires on:

* Attempting to write directly to a field (`FOO.field = some_val`) or
  array entry (`FOO.array_field[0] = val`)
* Taking a mutable reference to the `const` item (`&mut FOO`), including
  through an autoderef `FOO.some_mut_self_method()`

The lint message explains that since each use of a constant creates a
new temporary, the original `const` item will not be modified.
