  Abrupt completion when getting toString method
info: |
  Runtime Semantics: TrimString ( string, where )
  1. Let str be ? RequireObjectCoercible(string).
  2. Let S be ? ToString(str).
   ...

  ToString ( argument )
  If argument is Object:
    1. Let primValue be ? ToPrimitive(argument, hint String).
   ...

  ToPrimitive ( input [, PreferredType ])
   ...
    b. Else if PreferredType is hint String, let hint be "string".
   ...
    d. Let exoticToPrim be ? GetMethod(input, @@toPrimitive)
    e. If exoticToPrim is not undefined, then
      i. Let result be ? Call(exoticToPrim, input, « hint »).
      ii. If Type(result) is not Object, return result.
      iii. Throw a TypeError exception.
    f. If hint is "default", set hint to "number".
    g. Return ? OrdinaryToPrimitive(input, hint).
   ...

  OrdinaryToPrimitive( O, hint )
   ...
    3. If hint is "string", then
      a. Let methodNames be « "toString", "valueOf" ».
   ...
    5. For each name in methodNames in List order, do
      a. Let method be ? Get(O, name).
