Ever wonder why `identity("")` typechecks to
`scala.this.Predef.identity("")`?
It turns out that `mkAttributedRef` was importing
`q"$scalaPackageClass.this.Predef._"` for all these years,
rather than `q"$scalaModule.Predef._"`.
This commit makes `mkAttributedRef` special case static owners
by referring the the corresponding module, instead.

I resisted the urge to fix "aksTypeCompletion" for as long
as I possibly could. While I was there I threw in what seem
to be like significant output improvements, but you tell me.

some tests (unreachability, exhaustivity, @switch annotation checking) are still run under -Xoldpatmat,
but that will change before we go into RC mode (then the test/ partest of this commit will be reverted)
removed irrelevant dependency on patmat

*** Important note for busy commit log skimmers ***
Symbol method "fullName" has been trying to serve the dual role of "how
to print a symbol" and "how to find a class file." It cannot serve both
these roles simultaneously, primarily because of package objects but
other little things as well. Since in the majority of situations we want
the one which corresponds to the idealized scala world, not the grubby
bytecode, I went with that for fullName. When you require the path to a
class (e.g. you are calling Class.forName) you should use javaClassName.
package foo { package object bar { class Bippy } }
If sym is Bippy's symbol, then
sym.fullName == foo.bar.Bippy
sym.javaClassName == foo.bar.package.Bippy
*** End important note ***
There are many situations where we (until now) forewent revealing
everything we knew about a type mismatch. For instance, this isn't very
helpful of scalac (at least in those more common cases where you didn't
define type X on the previous repl line.)
scala> type X = Int
defined type alias X
scala> def f(x: X): Byte = x
<console>:8: error: type mismatch;
found : X
required: Byte
def f(x: X): Byte = x
^
Now it says:
found : X
(which expands to) Int
required: Byte
def f(x: X): Byte = x
^
In addition I rearchitected a number of methods involving:
- finding a symbol's owner
- calculating a symbol's name
- determining whether to print a prefix
No review.

Major rewrite of the testing infrastructure for the presentation
compiler. Added several new tests that will be part of the nightly
build. Once the move to SBT is completed I will look into how to extract
the test infrastructure (as it should really not be living in the
compiler codebase). Review by dragos
