   Compute the type T implied for a value `v` matched by a pattern `pat` (with expected type `pt`).

   Compute the type T implied for a value `v` matched by a pattern `pat` (with expected type `pt`).

   Usually, this is the pattern's type because pattern matching implies instance-of checks.

   However, Stable Identifier and Literal patterns are matched using `==`, which does not imply a type for the binder that binds the matched value.

   See scala/bug#1503, scala/bug#5024: don't cast binders to types we're not sure they have

   TODO: update spec as follows (deviation between `**`):

   A pattern binder x@p consists of a pattern variable x and a pattern p. The type of the variable x is the static type T **IMPLIED BY** the pattern p. This pattern matches any value v matched by the pattern p **Deleted: , provided the run-time type of v is also an instance of T, ** and it binds the variable name to that value.

   Addition: A pattern `p` _implies_ a type `T` if the pattern matches only values of the type `T`.
