…ake transition over hir::ItemKind simpler
Refactor inlining decisions so that inexpensive criteria are considered first: 1. Based on code generation attributes. 2. Based on MIR availability (examines call graph). 3. Based on MIR body.
For example, gdb:

For browsers that support woff2 (most modern ones: https://caniuse.com/woff2), this offers a reduction in download size for these two fonts from 362k to 257k (32% reduction). It decreases the total page size for `struct.String.html` (counting all subresources) by about 2.5%. If this is interesting, I'm happy to apply the same treatment to the other fonts, but these two are the biggest.
…, r=jyn514 Make ItemKind::ExternCrate looks like hir::ItemKind::ExternCrate to make transition over hir::ItemKind simpler It was surprisingly difficult to make this change, mostly because of two issues: * We now store the `ExternCrate` name in the parent struct (`clean::Item`), which forced me to modify the json conversion code a bit more than expected. * The second problem was that, since we now have a `Some(name)`, it was trying to render it, ending up in a panic because we ended up in a `unreachable` statement. The solution was simply to add `!item.is_extern_crate()` in `formats::renderer` before calling `cx.item(item, &cache)?;`. I'll continue to replace all the `clean::ItemKind` variants one by one until it looks exactly like `hir::ItemKind`. Then we'll simply discard the rustdoc type. Once this done, we'll be able to discard `clean::Item` too to use `hir::Item`. r? ``@jyn514``

Set codegen thread names
Set names on threads spawned during codegen. Various debugging and profiling tools can take advantage of this to show a more useful identifier for threads.
For example, gdb will show thread names in `info threads`:
