Clang 3.1 has more warnings enabled by default than GCC.
Combined with -Werror, they cause the build to fail
unnecessarily.  if the name of our compiler ends in "clang",
add the necessary extra -Wno options.  Ideally we would add
these flags unconditionally, as GCC is supposed to ignore
unknown -Wno flags, but apple's llvm-gcc doesn't.

Fixes #2878.

Periodically browse MHeap's freelists for long unused spans and release them if any.

Current hardcoded settings:
        - GC is forced if none occured over the last 2 minutes.
        - spans are handed back after 5 minutes of uselessness.

SysUnused (for Unix) is a wrapper on madvise MADV_DONTNEED on Linux and MADV_FREE on BSDs.

go/doc: move Examples to go/ast
cmd/go: use go/doc to read examples
src/pkg: update examples to use new convention

This is to make whole file examples more readable. When presented as a
complete function, preceding an Example with its output is confusing.
The new convention is to put the expected output in the final comment
of the example, preceded by the string "output:" (case insensitive).

An idiomatic example looks like this:

// This example demonstrates Foo by doing bar and quux.
func ExampleFoo() {
        // example body that does bar and quux

        // Output:
        // example output
}

Also: Simplified handling of selector expressions. As a result, complicated
multi-line expressions containing selectors and calls/indices with arguments
broken accross lines don't get indented the same way as before, but the change
is minimal (see tests) and there's no such code in the std library. It seems
a worthwhile compromise given the much simpler code.
