48fa974211 Suggest correct syntax when writing type arg instead of assoc type 
When confusing an associated type with a type argument, suggest the
appropriate syntax.

Given `Iterator<isize>`, suggest `Iterator<Item = isize>`.

f3e9b1a703 in which the E0618 "expected function" diagnostic gets a makeover 
Now the main span focuses on the erroneous not-a-function callee,
while showing the entire call expression is relegated to a secondary
span. In the case where the erroneous callee is itself a call, we
point out the definition, and, if the call expression spans multiple
lines, tentatively suggest a semicolon (because we suspect that the
"outer" call is actually supposed to be a tuple).

The new `bug!` assertion is, in fact, safe (`confirm_builtin_call` is
only called by `check_call`, which is only called with a first arg of
kind `ExprKind::Call` in `check_expr_kind`).

Resolves #51055.

5b0223e8c6 Reword rustc_on_unimplemented errors for Iterator 
- Detect one element array of `Range` type, which is potentially a typo:
   `for _ in [0..10] {}` where iterating between `0` and `10` was intended.
   (#23141)
 - Suggest `.bytes()` and `.chars()` for `String`.
 - Suggest borrowing or `.iter()` on arrays (#36391)
 - Suggest using range literal when iterating on integers (#34353)
 - Do not suggest `.iter()` by default (#50773, #46806)

88e9af0375 Fix doc link 
The link for comparison:

-   https://doc.rust-lang.org/book/second-edition/ch19-04-advanced-types.html#dynamically-sized-types--sized (broken)

-   https://doc.rust-lang.org/book/second-edition/ch19-04-advanced-types.html#dynamically-sized-types-and-sized (fixed)

This commit is the result of (first) searching via:

    find src -type f -print0 | xargs -0 fgrep -l dynamically-sized-types--sized

and then replacing all relevant occurrences via:

    find src/{libcore,test/ui} -type f -print0 | xargs -0 sed -i.bak \
      s/dynamically-sized-types--sized/dynamically-sized-types-and-sized/g
    find src/{libcore,test/ui} -type f -name '*.bak' -print0 | xargs -0 rm

(Note: Commands run on macOS 10.13 (BSD).  `sed -i.bak` should work on
GNU/Linux as well, but not tested.)
