Mode elimination ramps up in difficulty now, so I pursued
other forms of code hygiene.

It becomes context mode "TypeConstructor".
|
| | | | | |

Consolidating the scattered typer state in Context, where it's
relatively easy to keep an eye on, rather than threaded throughout
the typer in sneaky/sticky bitmasks. The general pattern will be
what was once an explicitly passed around bit in Mode becomes
an implicitly propagated-as-appropriate bit in Context.
In this commit:
ALTmode becomes context mode "PatternAlternative"
STARmode becomes context mode "StarPatterns"
SUPERCONSTRmode becomes context mode "SuperInit"

Attempting to reduce the frequency of low-level operations
with modes. I mean stuff like this:
if ((mode & (EXPRmode | LHSmode)) == EXPRmode)
THey don't make those ten line boolean guards any easier
to understand. Hopefully this will lead us toward eliminating
some of the modes entirely, or at least better isolating
their logic rather than having it interspersed at arbitrary
points throughout the typer.
Modes are in their entirety a leaked implementation detail.
Typing a tree requires a tree and optionally an expected type.
It shouldn't require a bucket of state bits. In subsequent
commits I will start eliminating them.
This commit also breaks adapt down into more digestible chunks.

A serious issue: partest would launch the same test multiple
times if a test path was given in multiple forms (e.g. absolute
and relative paths.) Unfortunately all those tests would share
the same logfile, output directory, etc. which would predictably
lead to explosions.
Since overwriting classfiles while being loaded can lead to
jvm core dumps, it's possible this is involved in recent jvm
crashes and other test breakdowns.
This commit also alters the default partest verbosity to only
full print test transcripts under --verbose.

Exploit SI-6446 fix to move old pending tests for plugins to the
active pool.
Also, nuance the partest runner to allow the compiler to crash
with a FatalError if a check file is present.
Some of the plugin tests make phase assembly throw.
One of the legacy tests was moved back to pending:
There seems to be a race for who shall be deemed truly dependent.
Back to pending for you!

The old behavior was that Plugin.loadAllFrom took a distinct
list of plugin locations.
The broken behavior incorrectly punted to the pruning
algorithm in Plugins.loadPlugins$pick.
The new behavior is to distinctify the list of class names
to load.
This is more robust; under the old scheme, specifying the
continuations.jar under two file names would fail as
described in the ticket.
Pruning a plugin by disabling (-Xplugin-disable) or because
it steps on someone else's phase name suffers the same
defect. There is no way to tell the plugin it has been
benched. And you know that global I gave you? Can I
have it back?

The nondeterminism presently showing itself in
presentation/implicit-member is a consequence of the
presentation compiler tests relying on details of the
behavior of toString calls. We need to stomp this out,
but it will take a while. Based on the check file
changes enclosed with this commit, this will suffice
for the presentation compiler tests. A broader assault
will have to take place, but not yet.

The original commit message (from 54a84a36d5):
SI-6548 reflection correctly enters jinners
When completing Java classes, runtime reflection enumerates their
fields, methods, constructors and inner classes, loads them and
enters them into either the instance part (ClassSymbol) or the
static part (ModuleSymbol).
However unlike fields, methods and constructors, inner classes don't
need to be entered explicitly - they are entered implicitly when
being loaded.
This patch fixes the double-enter problem, make sure that enter-on-load
uses the correct owner, and also hardens jclassAsScala against double
enters that can occur in a different scenario.

The optimizer behaves unexpectedly smartly, stripping off unused private
methods. Unfortunately, sometimes private methods might be compiled down
to public Java methods, so stripping them off might lead to binary
incompatibilities.
This particular commit recovers from this problem caused by
https://github.com/scala/scala/commit/5e715396af.

SI-7492 Remove -Ystruct-dispatch and associated code

This means that the private option is gone as well as the untested
code for no-cache and mono-cache and the non-working code for
invoke-dynamic.
poly-cache is now always used. For the future it probably makes more
sense to let the backend decide how it wants to treat structural
dispatch instead of allowing the user to “mix and match” backends
with structural dispatch implementations.

This is a variation on the previous commit which excludes
named type parameters, so this works
def f(x: Class[_]) = x.foo.bar
But this does not:
def f[T](x: Class[T]) = x.foo.bar
This seems undesirable to me, but I offer it in case it makes
the patch more attractive to others.

Also fixes SI-5459.
Look, you don't have to redeclare the bounds, isn't it exciting?
For instance, there are eight places in JavaMirrors with this:
jTypeVariable[_ <: GenericDeclaration]
After this code is in starr, those can look like this:
jTypeVariable[_]
Since TypeVariable's definition looks like this:
interface TypeVariable<D extends GenericDeclaration>
We already know that!

The previous fix uses Thread.stop to stop the threads which
drain outputs, but should do something orderly.
This commit interrupts the threads, which must check isInterrupted
before attempting further i/o.
The reading thread will suppress either the interruption or the
IOException cited in the ticket.
Similarly, i/o handlers must preserve and communicate interrupted
status.
The modest goal of this fix is to ameliorate any stack traces
when the process is destroyed.
The test runs itself as a sample process with output.
