The symbol loader need not create and populate package
symbols merely because there is a directory somewhere.
Every package created based on the existence of a directory
should contain a classfile, either directly or indirectly.
SI-5923 instantiates targs in deferred macro applications

In January I submitted a pull request that, as I thought back then,
fixes SI-5923: https://github.com/scala/scala/commit/fe60284769.
The pull request was merged, and everyone was happy that the bug got fixed.

Unfortunately, the fix was: a) incomplete, b) broke something else,
as noticed by Miles in https://groups.google.com/d/topic/scala-internals/7pA9CiiD3u8/discussion.

Now we got a real fix in 2.10.x (https://github.com/scala/scala/commit/90ac5c4e13),
and it's my pleasure to port it to master.
macroExpandAll is now triggered in all invocations of typed

This is a port of https://github.com/scala/scala/commit/bb73b9669a from 2.10.x.
SI-7167 implicit macros decide what is divergence

This is a port of https://github.com/scala/scala/commit/8168f118c9 from 2.10.x,
with an additional change to the `enclosingImplicits` and `openImplicits` APIs,
which encapsulates tuples of `pt` and `tree` into `ImplicitCandidate`.
SI-7047 fixes silent for c.inferImplicitXXX

This is a port of https://github.com/scala/scala/commit/b4da864247 from 2.10.x.

This is a port of https://github.com/scala/scala/commit/4e64a2731d from 2.10.x.
SI-7469 Make @deprecated elems in scala.concurrent private[scala]

They can't be removed yet because scala.actors depends on it.
SI-7469 Remove deprecated elements in s.u.parsing.combinator
SI-7469 Remove @deprecated MurmurHash elements
SI-7469 Remove @deprecated scala.util.parsing.ast
SI-7476 Add documentation to GenericTraversableTemplate
Fix formatting for couple of docs in the compiler

Source code on scaladoc for the virtual pattern matcher was not being
correctly identified as such. Also, I had to use an html code tag instead
of backticks when referring to the __match identifier, otherwise the
double underscore would be treated as start-of-underline wiki markup.
