2803: Fix various names, e.g. Iterator not resolving in core prelude r=matklad a=flodiebold
Basically, `Iterator` is re-exported via several steps, which happened to not be
resolved yet when we got to the prelude import, but since the name resolved to
the reexport from `core::iter` (just to no actual items), we gave up trying to
resolve it further.
Maybe part of the problem is that we can have
`PartialResolvedImport::Unresolved` or `PartialResolvedImport::Indeterminate`
with `None` in all namespaces, and handle them differently.
Fixes#2683.

When processing a change with added libraries, we used
`Default::default` for `SourceRoot` which sets `is_library` to false.
Since we use `is_library` to decide whether to use low or high
durability, I believe that this caused us to mark many library
dependencies as having low durability and thus increased the size of the
graph that salsa needed to verify on every change.
Based on my initial tests this speeds up the `CrateDefMapQuery` on
rust-analyzer from about ~64ms to ~14ms and reduces the number of
validations for the query from over 60k to about 7k.

2726: Improve profiling output when duration filter is specified r=matklad a=michalt

- Convert to millis for comparisons, since that's the unit used both

The `-` turned into a `+` during a refactoring.
The original issue was caused by `Read` resolving wrongly to a trait without
type parameters instead of a struct with one parameter; this only fixes the
crash, not the wrong resolution.
This change:
- introduces `compute_crate_def_map` query and renames
`CrateDefMap::crate_def_map_query` for consistency,
- annotates `crate_def_map` as `salsa::transparent` and adds a
top-level `crate_def_map` wrapper function around that starts the
profiler and immediately calls into `compute_crate_def_map` query.
This allows us to better understand where we spent the time, in
particular, how much is spent in the recomputaiton and how much in
salsa.
Example output (where we don't actually re-compute anything, but the
query still takes a non-trivial amount of time):
```
211ms - handle_inlay_hints
150ms - get_inlay_hints
150ms - SourceAnalyzer::new
65ms - def_with_body_from_child_node
65ms - analyze_container
65ms - analyze_container
65ms - Module::from_definition
65ms - Module::from_file
65ms - crate_def_map
1ms - parse_macro_query (6 calls)
0ms - raw_items_query (1 calls)
64ms - ???

When calling a function, argument-position impl Trait is transparent; same for
return-position impl Trait when inside the function. So in these cases, we need
to represent that type not by `Ty::Opaque`, but by a type variable that can be
unified with whatever flows into there.
2559: Add some granularity to syntax highlighting. r=matklad a=omerbenamram
Hi,
I wanted to start using `rust-analyzer` a bit more frequently - one of the main blockers for me so far was the highlighting.
I just discovered it's possible to override the default colors with `ralsp.<something>` setting without waiting for #2061!
However, the current implementation was lumping a bunch of different tokens into `type` and `literal`.
The golden standard IMO is what Clion is currently doing (and is my current daily driver for rust).
Clion allows users to control the coloring for specific literal kinds, and the default is to distinguish between them (numerics get a different color from strings, and special colors for bytestrings).
I've also splitted the builtin types, which are also allowed to be highlighted speratly.
My goal is to match the default experience I'm getting with clion.
The only blockers now I think is that `rust-analyzer` doesn't corrently infer types in some situations, so the highlighting information is incorrect in those cases.
This is what it looks like so far (with colors overriden to match clion's theme):
![image](https://user-images.githubusercontent.com/2467993/70848219-ccd97900-1e76-11ea-89e1-2e467cfcc9fb.png)
If there are any other changes you feel is necessary let me know.
I did leave the default colors to match the current behavior, since I'm not familiar with the colors for this theme, I added some random (different) colors in the test to check that it indeed was working.

2552: fix goto definition when inbetween tokens r=matklad a=succcubbus
fixes both goto_definition and goto_type_definition.
before, when running goto between some non-trivia token and an
identifier, goto would be attempted for the non-trivia token.
but this does not make sense for e.g. L_PAREN or COLONCOLON only for
IDENTs.
this resulted in goto actions not working when running them on the first
character of some identifier e.g. for `module::<|>method()` or
`method(<|>parameter)`.
now only IDENTs will be searched for in goto actions, though i'm not sure
if this is correct or if goto should also work for some other token types.

SourceAnalyzer didn't work properly within expression macro expansions because
it didn't find the enclosing function. Fix this by going up the expansion chain
to find ancestors. This makes the test work, but apparently in real usage it's
still not working.
If we are expecting a `&Foo` and get a `&something`, when checking the
`something`, we are *expecting* a `Foo`, but we shouldn't try to unify whatever
we get with that expectation, because it could actually be a `&Foo`, and `&&Foo`
coerces to `&Foo`. So this fixes quite a few false type mismatches.
2479: Add expansion infrastructure for derive macros r=matklad a=flodiebold
I thought I'd experiment a bit with attribute macro/derive expansion, and here's what I've got so far. It has dummy implementations of the Copy / Clone derives, to show that the approach works; it doesn't add any attribute macro support, but I think that fits into the architecture.
Basically, during raw item collection, we look at the attributes and generate macro calls for them if necessary. Currently I only do this for derives, and just add the derive macro calls as separate calls next to the item. I think for derives, it's important that they don't obscure the actual item, since they can't actually change it (e.g. sending the item token tree through macro expansion unnecessarily might make completion within it more complicated).
Attribute macros would have to be recognized at that stage and replace the item (i.e., the raw item collector will just emit an attribute macro call, and not the item). I think when we implement this, we should try to recognize known inert attributes, so that we don't do macro expansion unnecessarily; anything that isn't known needs to be treated as a possible attribute macro call (since the raw item collector can't resolve the macro yet).
There's basically no name resolution for attribute macros implemented, I just hardcoded the built-in derives. In the future, the built-ins should work within the normal name resolution infrastructure; the problem there is that the builtin stubs in `std` use macros 2.0, which we don't support yet (and adding support is outside the scope of this).
One aspect that I don't really have a solution for, but I don't know how important it is, is removing the attribute itself from its input. I'm pretty sure rustc leaves out the attribute macro from the input, but to do that, we'd have to create a completely new syntax node. I guess we could do it when / after converting to a token tree.
