Only suggest removing semicolon when expression is compatible with `impl Trait`
https://github.com/rust-lang/rust/issues/54771#issuecomment-476423690
> It still needs checking that the last statement's expr can actually conform to the trait, but the naïve behavior is there.
Only suggest removing a semicolon when the type behind the semicolon actually implements the trait in an RPIT `-> impl Trait`. Also upgrade the label that suggests removing the semicolon to a suggestion (should it be verbose?).
cc #54771
When a `macro_rules! foo { ... }` invocation is compiled the name used
is `foo`, not `macro_rules!`. This is different to all other macro
invocations, and confused me when I was inserted debugging println
statements for macro evaluation.
This commit changes it to `macro_rules` (or just `macro`), which is what
I expected. There are no externally visible changes.

Allow multiple derefs to be splitted in deref_separator
Previously in #95649 only a single deref within projection was supported and multiple derefs caused a bunch of issues, this PR fixes those issues.

Suggest replacing `typeof(...)` with an actual type
This PR adds suggestion to replace `typeof(...)` with an actual type of `...`, for example in case of `typeof(1)` we suggest replacing it with `i32`.
If the expression
1. Is not const (`{ let a = 1; let _: typeof(a); }`)
2. Can't be found (`let _: typeof(this_variable_does_not_exist)`)
3. Or has non-suggestable type (closure, generator, error, etc)
we don't suggest anything.
The 1 one is sad, but it's not clear how to support non-consts expressions for `typeof`.

Make def names and HIR names consistent.
The name in the `DefKey` is interned to create the `DefId`, so it does not
require any query to access. This can be leveraged to avoid a few useless
HIR accesses for names.
~In order to achieve that, generic parameters created from universal
impl-trait are given the pretty-printed ast as a name, instead of
`{{opaque}}`.~
~Drive-by: the `TyCtxt::opt_item_name` used a dummy span for non-local
definitions. We have access to `def_ident_span`, so we use it.~
We may sometimes emit an `invoke` instead of a `call` for inline
assembly during the MIR -> LLVM IR lowering. But we failed to update
the IR builder's current basic block before writing the results to the
outputs. This would result in invalid IR because the basic block would
end in a `store` instruction, which isn't a valid terminator.
