bc4810d907 Fix impl Trait Lifetime Handling 
After this change, impl Trait existentials are
desugared to a new `abstract type` definition
paired with a set of lifetimes to apply.

In-scope generics are included as parents of the
`abstract type` generics. Parent regions are
replaced with static, and parent regions
referenced in the `impl Trait` type are duplicated
at the end of the `abstract type`'s generics.

779fc372c7 Move E0562 to librustc from librustc_typeck 
With the check for impl trait moving from type checking to HIR lowering
the error needs to move too.

4b8bf391fd Auto merge of #44735 - tirr-c:issue-42143, r=arielb1 
Friendlier error message for closure argument type mismatch

Rebased #42270.
Fixes #42143.

---

`test.rs`:

```rust
fn main() {
    foo(|_: i32, _: usize| ());
}

fn foo<F>(_: F) where F: Fn(&str, usize) {}
```

Before:

```
error[E0281]: type mismatch: `[closure@test.rs:2:9: 2:30]` implements the trait `std::ops::Fn<(i32, usize)>`, but the trait `for<'r> std::ops::Fn<(&'r str, usize)>` is required
 --> test.rs:2:5
  |
2 |     foo(|_: i32, _: usize| ());
  |     ^^^ --------------------- implements `std::ops::Fn<(i32, usize)>`
  |     |
  |     expected &str, found i32
  |     requires `for<'r> std::ops::Fn<(&'r str, usize)>`
  |
  = note: required by `foo`
```

After (early):

```
error[E0631]: type mismatch in closure arguments
 --> test.rs:2:5
  |
2 |     foo(|_: i32, _: usize| ());
  |     ^^^ --------------------- takes arguments of type `i32` and `usize`
  |     |
  |     expected arguments of type `&str` and `usize`
  |
  = note: required by `foo`
```

After (current):

```
error[E0631]: type mismatch in closure arguments
 --> test.rs:2:5
  |
2 |     foo(|_: i32, _: usize| ());
  |     ^^^ --------------------- found signature of `fn(i32, usize) -> _`
  |     |
  |     expected signature of `for<'r> fn(&'r str, usize) -> _`
  |
  = note: required by `foo`
```

~~Compiler output has been changed, and a few tests are failing. Help me writing/fixing tests!~~

Removed as many "```ignore" as possible. 
Replaced by adding extra imports, adding hidden code (`# ...`), modifying
examples to be runnable (sorry Homura), specifying non-Rust code, and
converting to should_panic, no_run, or compile_fail.

Remaining "```ignore"s received an explanation why they are being ignored.

4358e35fda Implementation of repr struct alignment RFC 1358. 
The main changes around rustc::ty::Layout::struct and rustc_trans:adt:
* Added primitive_align field which stores alignment before repr align
* Always emit field padding when generating the LLVM struct fields
* Added methods for adjusting field indexes from the layout index to the
  LLVM struct field index

The main user of this information is rustc_trans::adt::struct_llfields
which determines the LLVM fields to be used by LLVM, including padding
fields.
