SI-7265 General test for spec version

The test for isJavaAtLeast uses the specification.version.
The method argument must have the form "major.minor".
The scaladoc is updated to reflect the new reality and a
test is added under junit.
Note that this implementation aims to be a simple
compromise between the functional and imperative camps,
that is, to be free of both closures and while loops.
And to elicit no cruft like regexes and wrappers for strings.
No doubt even more could be done in this department, but we
don't wish to spoil the fun on codegolf.stackexchange.com.
However, we might decide to sponsor a new site:
codereviewpingpong.com
For 2.10.x, javaSpecVersion is provided as a private member.
The active test is under `run` and the `junit` test must
bide its time in `pending`.
For 2.11, the private members can be public and the app test
replaced with the unit test.

SI-7649 Fix positions for reshaped tag materializers

Calls to `materializeClassTag[T]` are replaced during reification with
`implicitly[ClassTag[T]]` in the `reify` macro. This is done to avoid
referring to symbols in scala-compiler.jar. Class- and Type-Tag
materialization is treated in the same way.
This commit positions the replacement trees to avoid triggering
assertions under -Yrangepos.

SI-7617 typedAssign no longer expands lhs

This makes sure that setter and updateDynamic macros work as intended
rather than in some cases expanding incorrectly or prematurely.
Setter invocations are desugared from assignments of values to getters.
If a typecheck of an assignment's lhs yields an invocation of a getter,
then the assignment is rewritten into an invocation of a setter. However
if a getter is a macro, then it just expands, destroying the prerequisite
for desugaring. Therefore we need to disable expansion for the typecheck
of an lhs.
Similar thing happens to updateDynamic that first desugars a getter
invocation into q"$target.updateDynamic($fieldName)" and then expects
typedAssign to rewrite the corresponding Assign node into an additional
application of a partially applied updateDynamic to a rhs. Here we also
need to disable the typecheck of an lhs, because macros cannot be
partially applied.

SI-7638 Superaccessor lookup after specialization
|

The crash was caused by a symbol lookup to rewire the super calls,
done after pickler, but specialization added new traits and new
members, thus making the super rewiring impossible. To avoid such
problems, this patch moves symbol lookup after specialization,
so the changes done by specialization (and miniboxing) become
visible to mixin.
NOTE: This patch will be followed by a similar patch to master.

SI-7668 Better return type inheritance for dep. method types
|

Return type inheritance already handles substitution of
type parameters of the overriding method for those of the
overriding.
This commit extends this to do the same for parameter symbols.

The pattern matcher's analysis was correctly finding
models under which the match in the enclosed test
could fail. But, when trying to render that model
as a counter example, it ran into an internal inconsistency
and gave up.
That inconsistency arose from VariableAssignment, which:
> turn the variable assignments into a tree
> the root is the scrutinee (x1), edges are labelled
> by the fields that are assigned a node is a variable
> example (which is later turned into a counter example)
In the process, it notes the unreachable case `V2 = NotHandled`,
which can only arise if `V1 = Op`, ie the scrutinee is `Op(NotHandled())`.
V2 is assosicated with the path `x1.arg`. The code then looked for
any variable assosicated with the prefix `x1` and registered that its
field `arg` was assosicated with this variable assignment.
However, the assignment for `V1 = NotHandled` (another missing case)
is also associated with the path `x1`. Registering this field makes
no sense here; we should only do that for `Op`.
This commit conditionally registers the fields based on the class
of `VariableAssignment#cls`. We no longer hit the inconsistency in
`VariableAssignment#allFieldAssignmentsLegal`.
This favourably changes the results of two existing tests.
I had to tweak the counter example pruning to avoid relying on
CounterExample.==, which is flaky in the light of Nil and List().
It is possible to have:
A, B where A != B && A.coveredBy(B) && B.coveredBy(A)
Luckily it is straightforward to implement pruning entirely with
coveredBy.

“This class is used internally.” — No, it isn't.
It isn't used anywhere else either and it doesn't add much benefit,
considering that it lacks documentation and has no tests at all.

Regressed in e28c3edda4. That commit encoded upper/lower bounds
of Any/Nothing as EmptyTree, which were triggering the .isEmpty
check in Namers#TypeTreeSubstitutor and resulting in the default
getter having TypeTree() as the return type. This resulted in a
"missing parmameter type" error.
This commit tightens up that condition to only consider empty
TypeTrees (those wrapping null or NoType.)

SI-7695 Macro debug output on -explaintypes

It looks like checkConforms should wait for error before
using explainTypes, rather than turning on macro debug
trace if explaintypes is set.
In particular, macro debug output is Console.println
instead of reporter.echo or similar, so partest can't
test it.

The REPL :java -app command is a convenience to locate

new style delayedEndpoints on the class before it
falls back to showing the apply method of the
delayedInit$body closure.
