Also, drop AbstractFunction for parent of anonymous subclass of
function type that must have its class spun up at compile time
(rather than at linkage time by LambdaMetaFactory).
This revealed an old problem with typedTemplate, in which
parent types may be normalized at the level of trees,
while this change does not get propagated to the class's info
in time for the constructor to be located when we type check
the primary constructor.

`missing1.foo(missing2)` now reports `missing1` and `missing2` as
not found. Previously, only the first was reported.
The arguments are typed with an expected type ErrorType. We propagate
this through as the inferred type of anonymous function parameters
to avoid issuing cascading "missing parameter type" errors in code
like:
scala> Nil.mapp(x => abracadabra)
<console>:8: error: value mapp is not a member of object Nil
Nil.mapp(x => abracadabra)
^
<console>:8: error: not found: value abracadabra
Nil.mapp(x => abracadabra)
^
This was in response to unwanted changes in the output of existing
neg tests; no new test is added.
Similarly, we refine the errors in neg/t6436b.scala by to avoid
cascaded errors after:
type mismatch; found: StringContext, required: ?{def q: ?}

The parser hole I found while working on the generated positions
serves as the umbrella for a host of improvements. Upgraded
positions assigned during some specific challenging situations mostly
involving the creation of synthetic trees, e.g. for comprehensions
and closures. While doing so improved some error messages.
Eliminated some of the most glaring duplication in the parser.
It's written like there is some payoff associated with being
spectacularly imperative. Not so far.
