ef2b84ddf1 introduce hir debugging infra 
This is to make debugging rust-analyzer easier.

The idea is that `dbg!(krate.debug(db))` will print the actual, fuzzy
crate name, instead of precise ID. Debug printing infra is a separate
thing, to make sure that the actual hir doesn't have access to global
information.

Do not use `.debug` for `log::` logging: debugging executes queries,
and might introduce unneded dependencies to the crate graph

065d398701 Add trait obligations for where clauses when calling functions/methods 
E.g. if we call `foo<T: Into<u32>>(x)`, that adds an obligation that `x:
Into<u32>`, etc.

1834bae5b8 allow rustfmt to reorder imports 
This wasn't a right decision in the first place, the feature flag was
broken in the last rustfmt release, and syntax highlighting of imports
is more important anyway

a198d78bd1 cache chalk queries 
This gives a significant speedup, because chalk will call these
functions several times even withing a single revision. The only
significant one here is `impl_data`, but I figured it might be good to
cache others just for consistency.

The results I get are:

Before:

from scratch:   16.081457952s
no change:      15.846493ms
trivial change: 352.95592ms
comment change: 361.998408ms
const change:   457.629212ms

After:

from scratch:   14.910610278s
no change:      14.934647ms
trivial change: 85.633023ms
comment change: 96.433023ms
const change:   171.543296ms

Seems like a nice win!

8b7f58976b don't cache parses twice 
Before this commit, `Parse`s for original file ended up two times in
salsa's db: first, when we parse original file, and second, when we
parse macro or a file.

Given that parse trees are the worst ofenders in terms of memory, it
makes sense to make sure we store them only once.

f89d34be6a don't poison mutex around chalk 
We use panics for cancellation, so we could trigger panic while
holding the solver. std::sync::Mutex will be poisoned as a result,
which and all further attempts to use solver (from other threads) will
panic as well.

This commit switches to parking_lot::Mutex which just unlocks on panic.

Aleksey Kladov
5dc384132f introduce macro_arg intermediate query 
Currently, when expanding macros, we look at the source code
directly (we invoke ast_id_to_node query via to_node method).

This is less then ideal, because it make us re-expand macros after
every source change.

This commit establishes a salsa-firewall: a query to get macro call's
token tree. Unlike the syntax tree, token tree changes only if we
actually modify the macro itself.

a1ed53a4f1 More trait infrastructure 
- make it possible to get parent trait from method
 - add 'obligation' machinery for checking that a type implements a
   trait (and inferring facts about type variables from that)
 - handle type parameters of traits (to a certain degree)
 - improve the hacky implements check to cover enough cases to exercise the
   handling of traits with type parameters
 - basic canonicalization (will probably also be done by Chalk)

5270bca5f7 store macro def inside macro id 
This solves the problem of "macro expansion can't call into name
resolution, because name resolution calls back into macro expansion"

Because we store macro def as a part of call id, macro expansion just
knows the def!
