SI-7488 REPL javap finds new style delayedEndpoint

The REPL :java -app command is a convenience to locate
the body of DelayedInit code.  Now it will look for
new style delayedEndpoints on the class before it
falls back to showing the apply method of the
delayedInit$body closure.

SI-7592 Deprecate s.c.m.DefaultMapModel

“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.
SI-7679 Remove deprecated StandardScalaSettings#make
SI-7681 Remove dead code in s.t.n.s.AbsScalaSettings
SI-7681 Remove s.t.n.d.Changes (dead code)
SI-7681 Remove scala.tools.nsc.Phases
SI-7681 Clean up scala.reflect.internal.util.TableDef
... now that scala.tools.nsc.Phases is gone.

SI-7689 Fix typing regression with default arguments

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.
