922ff8e485 Refactor hir::Place 
For the following code
```rust
let c = || bar(foo.x, foo.x)
```

We generate two different `hir::Place`s for both `foo.x`.
Handling this adds overhead for analysis we need to do for RFC 2229.

We also want to store type information at each Projection to support
analysis as part of the RFC. This resembles what we have for
`mir::Place`

This commit modifies the Place as follows:
- Rename to `PlaceWithHirId`, where there `hir_id` is that of the
expressioin.
- Move any other information that describes the access out to another
struct now called `Place`.
- Removed `Span`, it can be accessed using the [hir
API](https://doc.rust-lang.org/nightly/nightly-rustc/rustc_middle/hir/map/struct.Map.html#method.span)
- Modify `Projection` to be a strucutre of its own, that currently only
contains the `ProjectionKind`.

Adding type information to projections wil be completed as part of https://github.com/rust-lang/project-rfc-2229/issues/5

Closes https://github.com/rust-lang/project-rfc-2229/issues/3
