Factor out the logic for mapping from a `LocId` into a diagnostic
location from check into sem_ir so it can be reused by lowering. Include
the function and instruction being lowered in the pretty stack trace.
Example stack trace:
```carbon
2. filename: examples/sieve.carbon
3. core/prelude/types/int.carbon:213:3: lowering function Core.Op(Core.IntLiteral as Core.ImplicitAs(i32))
fn Op[addr self: Self*](other: Self) = "int.sadd_assign";
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
4. core/prelude/operators/arithmetic.carbon:22:27: lowering call
fn Op[addr self: Self*](other: Other);
^~~~~~~~~~~~
```
