After the merge, the test/run/t7733 started to fail on Jenkins.
I tried to reproduce it locally but I couldn't so I think it's
system dependent failure. Per @retronym's suggestion I moved it to pending
to not block the whole merge.

Moved an existing test from `pending` to `pos`. Not sure why
it was moved to `pending` in the first place.
Adds a new test distilled from building Scalaz with 2.10.3-RC1.

I'm looking at the changes made in 47f35b587, which
prevented cyclic errors in class file parsing. That fix
is insufficient for, or otherwise complicit in, SI-7778, for
which I've enclosed a pending test.

Consider this pattern match translation, that occurs *before* refchecks:
scala> val e: java.lang.Enum[_] = java.util.concurrent.TimeUnit.SECONDS
scala> e match { case x => x }
<console>:9: error: type arguments [_$1] do not conform to class Enum's type parameter bounds [E <: Enum[E]]
e match { case x => x }
^
[[syntax trees at end of refchecks]] // <console>
package $line5 {
case <synthetic> val x1: Enum[_$1] = $line3.$read.$iw.$iw.e;
case4(){
matchEnd3(x1)
};
matchEnd3(x: Enum[_$1]){
x
}
RefChecks turns a blind eye to the non-conformant type `Enum[_$1]` in
the label defs because of `65340ed4ad2e`. (Incidentally, that is far
too broad, as I've noted in SI-7756.)
This commit extends this exception to cover the synthetic ValDef `x1`.
Commit log watchers might notice the similarities to SI-7694.

[nomaster] macro expansions are now auto-duplicated

The fix still requires macro developers to be careful about sharing trees
by references, because attributed DefTrees will still bring trouble.
However this is an improvement, because it doesn't make matters worse
and automatically fixes situations similar to one in the test.
A much more thorough discussion with a number of open questions left:
http://groups.google.com/group/scala-internals/browse_thread/thread/492560d941b315cc
Was fixed ages ago in master in one of the paradise backports.
Never got to 2.10.x, but it's very useful, so I'm backporting it now.

These are passed through from `InferencerContextErrors#applyErrorMsg`
to `withDisambiguation` as the `locals` parameter, which is promptly
ignored. This looks to be an unintended change in 39938bcc299.
Without this patch, the enclosed test case enters a pathalogical
disambiguation session, that not only flirts with unpleasant big-O
complexities, but also flails about appending "(in method foo)"
only to find that *all* occurences of the same-named type parameter
come from some method named "foo".

SI-7733 reflective packages now more consistent with scalac

Previously PackageScopes from scala.reflect ignored all classes that
had $'s in non-rightmost positions in their names.
Unfortunately this behaviour is inconsistent with how scalac does things,
and I reconciled this as usual, by pulling corresponding logic into
scala-reflect.jar and sharing it between runtime reflection and compiler.
This change has seprate pull requests for 2.10.x and 2.11.0. The latter
deprecates `scala.tools.nsc.util.ClassPath.isTraitImplementation`
whereas the former (which you're looking at right now) does not, because
we can't deprecated members in minor releases.

Back then when I implemented macros for inclusion in trunk (Spring 2012),
partest didn't support the _1, _2, ... convention for neg tests, so I had
to use toolboxes to test macro-generated exceptions.
Unfortunately toolboxes aren't very good with positions (mostly because
their inputs are almost always constructed without corresponding sources)
so I didn't notice that errors signalizing about macro-generated
exceptions actually don't carry positions with them because of a typo.
This patch fixes the oversight, but it doesn't need to be ported to master,
because over there everything's already fixed by one of the backports
from macro paradise.

This commit gets rid off code wrapping that was previously used by
toolbox to get into correct parsing mode. Instead combination of
templateStats/accept(EOF) is used. This is the same solution as the one
used in repl and built-in scriptRunner
This pull request doesn't attempt to generalize this approach in any
way and re-use it all over the place due to the caution of possible
accidental compatibility breakage. I plan to do it separately against
master.
Additionally there are a few more changes that make importers be aware
of positions and a test for that (via @jedesah).

SI-1980 A lint warning for by-name parameters in right assoc methods

The desugaring of right associative calls happens in the parser. This
eagerly evaluates the arguments (to preserve left-to-right evaluation
order the arguments are evaluated before the qualifier).
This is pretty surprising if the method being called has a by-name
parameter in the first parameter section.
This commit adds a warning under -Xlint when defining such a method.
The relevent spec snippets:
> SLS 4.6.1 says that call-by-name argument "is not evaluated at the point of function application, but instead is evaluated at each use within the function".
>
> But 6.12.3 offers:
> "If op is right- associative, the same operation is interpreted as { val x=e1; e2.op(x ) }, where x is a fresh name."

This is the notion that's come to be universally useful, so I suggest
we promote it to be universally accessible.
Note that the attached test incorrectly fails to report errors for
definitions coming from the empty package and for annotations. These
are bugs, and they are fixed in subsequent commits of this pull request.

As partest is now resolved from maven, `test/partest` uses `ant test.suite.init`
to determine the classpath (serialized to build/pack/partest.properties)
that's necessary to run `scala.tools.partest.nest.ConsoleRunner`.
Thus, partest gets exactly the same classpath, whether run from
the command line through `test/partest` or via `ant test`.
The version of partest we're using is specified by
properties defined in versions.properties (formerly `starr.number`).
Currently, we're using:
```
scala.binary.version=2.11.0-M4
partest.version.number=1.0-RC3
```
NOTES:
- The version of Scala being tested must be backwards binary compatible with
the version of Scala that was used to compile partest.
- Once 2.11 goes final, `scala.binary.version=2.11`, and `starr.version=2.11.0`.
- Need scalacheck on classpath for test/partest scalacheck tests.
- Removed atrophied ant tests (haven't been run/changed for at least two years
I checked 81d659141a as a "random" sample).
- Removed scalacheck. It's resolved as a partest dependency.
- For now, use a locally built scalap
- Kept the trace macro in the main repo (partest-extras)
- New targets for faster pr validation: test-core-opt, test-stab-opt
- Reused partest eclipse/intellij project to partest-extras
(note: the partest dependency is hard-coded)

In 65340ed4ad2e, parts of RefChecks were disabled when
we traversed into the results of the new pattern matcher.
Similar logic existed for the old pattern matcher, but in
that case the Match / CaseDef nodes still existed in the tree.
The new approach was too broad: important checks no longer
scrutinized the body of cases.
This commit turns the checks back on when it finds the remnants
of a case body, which appears as an application to a label def.

Fixing #ifdiff uncovered a latent bug in partest when it detects
paths to normalize in test log output. It would not normalize
file separators for test names with non-word characters.
This commit normalizes the test name to the ticket number as a
workaround until the next partest version is picked up.
It also fixes partest in this repo in case we've not yet switched
