Some scalac output is on stderr, and it's useful to see that
in the log file, especially for debugging.
Adds a line filter for logs, specified as "filter: pattern"
in the test source.
Backslashes are made forward only when detected as paths.
Test alignments:
Deprecations which do not pertain to the system under test
are corrected in the obvious way.
When testing deprecated API, suppress warnings by deprecating
the Test object.
Check files are updated with useful true warnings, instead of
running under -nowarn.
Language feature imports as required, instead of running under -language.
Language feature not required, such as casual use of postfix.
Heed useful warning.
Ignore broken warnings. (Rarely, -nowarn.)
Inliner warnings pop up under -optimise only, so for now, just
filter them out where they occur.
Debug output from the test required an update.

This brings all the files into line with the .gitattributes
settings, which should henceforth be automatically maintained
by git.

this uncovers a bug in toolboxes: https://issues.scala-lang.org/browse/SI-6007
however that bug is not critical, so it will be dealt with later

And grueling recovery from branch drift.
Merges a portion (and only a portion) of topic/inline into master.
The major changes which come with this merge are:
AnyVal is unsealed, can be extended directly.
ScalaObject is no longer with us.

Annotations are now supported by the reifier:
* AnnotationInfos from symbols get transformed back into mods.
* AnnotatedTypes are retained and are reified along with AnnotationInfos.
Reification is no magic, and reification of annotations especially:
* Annotations cannot refer to symbols defined inside the quasiquote.
This restriction is due to the fact that we need to erase locally defined
symbols before reifying to make subsequent reflective compilations succeed.
However, while doing that, we also need to make sure that we don't make
resulting ASTs non-compilable by removing essential information.
This is tricky, and it more or less works for TypeTrees, but
not for annotations that can contain arbitrary ASTs.
For more details look into the comments to Reifiers.scala.
* Classfile annotations that contain array arguments and are applied to types,
i.e. the ones that generate AnnotatedTypes, cannot be reified.
This is because of limitations of manifest infrastructure.
Typechecking "Array(mirror.LiteralAnnotArg(...))" would require the compiler
to produce a manifest for a path-dependent type, which cannot be done now.
