shim.rs: avoid creating `Call` terminators calling `Self`

Also contains some cleanup and doc comment additions so I could make sense of the code.

af97a117e5 shim.rs: call FnPtr, not Self 
The `Call` terminator only works with `FnDef` and `FnPtr` types.
It happened to work with `Self` so far because it was always
substituted with the real type before being used.

Track span of function in method calls, and use this in #[track_caller] 
Fixes #69977

When we parse a chain of method calls like `foo.a().b().c()`, each
`MethodCallExpr` gets assigned a span that starts at the beginning of
the call chain (`foo`). While this is useful for diagnostics, it means
that `Location::caller` will return the same location for every call
in a call chain.

This PR makes us separately record the span of the function name and
arguments for a method call (e.g. `b()` in `foo.a().b().c()`). This
`Span` is passed through HIR lowering and MIR building to
`TerminatorKind::Call`, where it is used in preference to
`Terminator.source_info.span` when determining `Location::caller`.

This new span is also useful for diagnostics where we want to emphasize
a particular method call - for an example, see

afd8a4e7ec Improve LocalDecl creation. 
This commit adds some new `LocalDecl` methods:
- `with_source_info`, a most general constructor.
- `new`, a variant of `with_source_info` which represents the most
  common use case.
- `internal` a modifying method (like the already present `immutable`).

It removes some old `LocalDecl` methods:
- `new_internal` and `new_local`, because they're subsumed by the new
  methods.
- `new_return_place`, because it was identical to `new_temp`.

Finally, it cleans up all the use sites.
