Eyeballing a sampling of the raw number of comparisons shows a drop
on the order of 20-30% almost everywhere. The test input data that
doesn't match that are some of sawtooth/rand/plateau distributions,
where there is no change in the number of comparisons; that is,
there are no situations where this makes *more* comparisons.

Fixes #2585.

The test for issue 3590 causes an error to be printed to stderr when run (although the error is obscured during go test std). This is confusing for people who get breakage in the net package as the error is harmless and most likely unrelated to their build breakage.

Given the way the test works, by reaching into the guts of the netFD, I can't see a way to silence the error without adding a bunch of code to support the test, therefore I am suggesting the test be removed before Go 1.1 ships.

Unexported field and method names that appear in the
export data (as part of some exported type) are fully
qualified with a package id (path). In some cases, a
package with that id was never exported for any other
use (i.e. only the path is of interest).

We must not create a "real" package in those cases
because we don't have a package name. Entering an
unnamed package into the map of imported packages
makes that package accessible for other imports.
Such a subsequent import may find the unnamed
package in the map, and reuse it. That reused and
imported package is then entered into the importing
file scope, still w/o a name. References to that
package cannot resolved after that. Was bug.

The lowering of ast.RangeStmt now has three distinct cases:

1) rangeIter for maps and strings; approximately:
    it = range x
    for {
      k, v, ok = next it
      if !ok { break }
      ...
    }
   The Range instruction and the interpreter's "iter"
   datatype are now restricted to these types.

2) rangeChan for channels; approximately:
    for {
      k, ok = <-x
      if !ok { break }
      ...
    }

3) rangeIndexed for slices, arrays, and *array; approximately:
    for k, l = 0, len(x); k < l; k++ {
      v = x[k]
      ...
    }

In all cases we now evaluate the side effects of the range expression
exactly once, per comments on http://code.google.com/p/go/issues/detail?id=4644.

However the exact spec wording is still being discussed in
https://golang.org/cl/7307083/.  Further (small)
changes may be required once the dust settles.
