TypeTree printing modified (SI-8447)
SI-8553 WrappedArray throws exception on lastIndexWhere when index out of range

Adds a check in `IndexedSeqOptimized#lastIndexWhere(A => Boolean, Int)`
to begin searching in the end of the collection if `end` is greater than
the collection's length.

SI-8185 Correct grammar for single-warning compilation run
SI-8609 Fix flattening of definitions and imports in quasiquotes

Quasiquotes allow to unquote trees with ..$ with block flattening
semantics to simplify composition:

  val onetwo = q"1; 2"
  val onetwothree = q"..$onetwo; 3" // same as q"1; 2; 3"

If there is no block it will be equivalent to $ unquoting:

  val one = q"1"
  val onetwo = q"..$one; 2" // same as q"1; 2"

But the inconsistency here is that currently only terms support
this single-element semantics. This commit extends this functionality
to also support definitions and imports. So that following code works:

  val q1 = q"val x = 1"
  val q2 = q"..$q1; val y = 2" // same as q"val x = 1; val y = 2"
SI-5905 Clarify test case

The language feature options are discovered reflectively, but it
is nice to enforce that expected options are supplied.

Short of that, the code string includes a rowdy postfix operator.

It still does enforce that at least one option was discovered.
adds MacroPlugin.pluginsIsBlackbox

This is an important omission in the current macro plugin API, which was
designed before the blackbox vs whitebox separation was implemented.

Even if one overrides pluginsTypedMacroBody and pluginsMacroExpand,
that would still be not enough to write a custom macro expander, because
typedImplicit1 uses isBlackbox, which is tightly coupled with the standard
way of reading/writing macro signatures.
macro args now correctly preserve range positions

Somewhen in the 2.11.0 development cycle we started duplicating macro arguments
for increased robustness. What wasn't taken into account though is that
Tree.duplicate destroys range positions. This commit fixes the problem.

2.10.x is unaffected by this bug, because it doesn't duplicate the args yet.
SI-8494 Restore filtering javap output

Regressed in support for new delayedEndPoint, where it must
pick what to filter for.

`s/claas/klass/` and similar.
SI-8494 Javap filter includes specialized

When filtering javap output, include specialized versions
of methods. For anonfuns, in particular, the apply$sp is
the method of interest.
SI-8503 Clean up interpolation of help message

We have interpolation now. This commit also moves an extra blank
line from the end to the middle of the message.
SI-8596 Fix rangepos crasher with defaults, poly methods

Regressed in SI-7915 / 3009a525b5

We should be deriving the position of the synthetic `Select`
from `basefun1`, rather than `basefun`. In the new, enclosed
test, the difference amounts to:

    new Container().typeParamAndDefaultArg[Any]()
    `------------ basefun1 --------------'
    `----------------- basefun ---------------'

For monomorphic methods, these are one and the same, which is
why `presentation/t7915` was working. I've extended that test
to a polymorphic method to check that hyperlink resolution works.
SI-8503 -version is info setting

And the Scala runner exits with 0 for info settings.

Producing the version string is consolidated.

The compiler driver uses the default settings hook to
short-circuit on -version.  That's to avoid creating
the compiler; really it should check shouldStopWithInfo
first, as the runner does.
SI-6409  Stream flatMap leaks memory if mapper returns many empties

Added Scaladoc explaining that this is necessary behavior, but closed ticket as wontfix.
