The underlying transformer has a by-name parameter for the
to provide the `to` tree, but this was strict in the layers
of API above.
Tree sharing is frowned upon in general as it leads to cross
talk when, e.g., the erasure typechecker mutates the
`tpe` field of the shared tree in different context.

Before this commit, multiple invocations of universe.showRaw used a
shared weak map that caches footnotes. If the two printed objects
have equal components printed as footnotes, e.g., an equal TypeRef,
the result of the second invocation depends on whether the object
has been collected (and removed from the weak map) or not.

- Language imports are preceding other imports
- Deleted empty file: InlineErasure
- Removed some unused private[parallel] methods in
scala/collection/parallel/package.scala
This removes hundreds of warnings when compiling with
"-Xlint -Ywarn-dead-code -Ywarn-unused -Ywarn-unused-import".

Adds query methods to the public reflection API for querying the
JAVA_ENUM and JAVA_ANNOTATION flags.
Didn't include JAVA_DEFAULTMETHOD because it does not correspond
to a real java classfile flag (just a non-abstract method in an
interface), and we want to clean the usage of this flag before adding
it to a public API.
The flags themselfs are not added to the reflection API. A comment in
api/FlagSets.scala says:
Q: I have a pretty flag. Can I put it here?
A: Only if there's a tree that cannot be built without it.
If you want to put a flag here so that it can be tested
against, introduce an `isXXX` method in one of the api.Symbols
classes instead.

This commit corrects many typos found in scaladocs, comments and
documentation. It should reduce a bit number of PRs which fix one
typo.
There are no changes in the 'real' code except one corrected name of
a JUnit test method and some error messages in exceptions. In the case
of typos in other method or field names etc., I just skipped them.
Obviously this commit doesn't fix all existing typos. I just generated
in IntelliJ the list of potential typos and looked through it quickly.

Avoid the widening bug for q. This resolution also suffers
from the inference of Any, which can trigger a warning and
an anxiety attack. But that's still better than doing the
wrong thing.

The reason for adding the SerialVersionUID annotations is to
be able to provide serialization stability throughout the 2.11.x
series. And since type tags (and exprs) have not been serializable
before, this does not break serialization for existing code.

- Make TypeCreator and TreeCreator extend Serializable.
- When replacing a SerializedTypeTag with a TypeTag or WeakTypeTag,
do not use scala.reflect.runtime.universe.rootMirror, since
it is unlikely to find user classes; instead, create a runtime
mirror using the context ClassLoader of the current thread.
Use the same logic for SerializedExpr.
- Remove writeObject/readObject methods from SerializedTypeTag
and SerializedExpr since they are unused.
- Add @throws annotation on writeReplace and readResolve methods.
- Handle SecurityException if the current thread cannot access the
context ClassLoader.
- To make type tags of primitive value classes serializable, make
PredefTypeCreator a top-level class. Otherwise, it would
retain a reference to the enclosing Universe,
rendering the TypeCreator non-serializable.
Binary compatibility:
- Keep nested PredefTypeCreator class to avoid backward binary
incompatible change.
- Keep `var` modifiers on the class parameters of
SerializedTypeTag for backward binary compatibility.
- Adds filter rules to forward binary compatibility whitelist:
- `TypeCreator`, `PredefTypeCreator`, and `TreeCreator` must now
extend from `Serializable`.
- Must have new class `scala.reflect.api.PredefTypeCreator`
to avoid problematic outer reference.

Due to the fact that all TypTrees are transformed into TypeTrees
during typechecking one couldn't treat typed type trees in the same
way as they treat untyped type trees.
This change implements support for pattern matching of TypeTrees as their
corresponding TypTree equivalent using tree preserved in the original.
The implementation itself is a trivial wrapping of regular TypTree
extractors into MaybeTypeTreeOriginal.

I just realized that our tag-based shortcuts were incomplete, because
they only work with root mirrors (doing just u.typeTag[T].tpe means that
the type is going to be resolved in u.rootMirror because that's the default).
This commit fixes this oversight. I'm hoping for 2.11.0-RC3, but also feel
free to reschedule to 2.12.0-M1 if it becomes clear that RC3 isn't happening.

This liftable hasn't been originally included in the set of standard
liftables due to following contradiction:
1. On one hand we can have identity lifting that seems to be quite
consistent with regular unquoting:
q"..${List(1,2)}" <==> q"1; 2"
q"${List(1,2)}" <==> q"s.c.i.List(1, 2)"
q"..${List(q"a", q"b")}” <==> q"a; b"
q"${List(q"a", q"b")}" <==> q"s.c.i.List(a, b)"
This is also consistent with how lisp unquoting works although they
get lifting for free thanks to homoiconicity:
// scala
scala> val x = List(q"a", q"b); q"f($x)"
q"f(s.c.i.List(a, b))"
// scheme
> (let [(x (list a b))] `(f ,x))
'(f (list a b))
2. On the other hand lifting is an operation that converts a value into
a code that when evaluated turns into the same value. In this sense
Liftable[Tree] means reification of a tree into a tree that
represents it, i.e.:
q"${List(q"a", q"b")}"
<==>
q"""s.c.i.List(Ident(TermName("a")), Ident(TermName("b")))"""
But I belive that such lifting will be very confusing for everyone
other than a few very advanced users.
This commit introduces the first option as a default Liftable for trees.

Previously one could match a partial function with match quasiquote:
scala> val q"$scrutinee match { case ..$cases }" = q"{ case Foo => Bar
}"
scrutinee: universe.Tree = <empty>
cases: List[universe.CaseDef] = List(case Foo => Bar)
This was quite annoying as it leaked encoding of partial functions as
Match trees with empty tree in place of scrutinee.
This commit make sure that matches and partial functions are disjoint
and don't match one another (while preserving original encoding under
the hood out of sight of the end user.)

SI-8331 make sure type select & applied type doesn't match terms

Due to tree re-use it used to be the fact that type quasiquotes could
match term trees. This commit makes sure selections and applied type and
type applied are all non-overlapping between q and tq.

As per Jason's feedback, these are now undeprecated, being aliases for
info and infoIn. I haven't touched the newly introduced setInfo family of
methods, because I think that on internal level we don't need setTypeSignature
anyway.

This is extremely important to enable cross-versioning Scala 2.10 codebases
against Scala 2.11 using Jason's trick with:
// TODO 2.11 Remove this after dropping 2.10.x support.
private object HasCompat { val compat = ??? }; import HasCompat._
def impl(c: Context)(...): ... = {

Unfortunately I have to revert b017629 because of SI-8303. There are projects
(e.g. slick) that use typeOf in annotations, which effectively means bye-bye.
