Latest macOS High Sierra changed how the wall time information
is exported into the commpage. Backward compatibility was partly
preserved, that is previous Go versions are basically forced to
go through a syscall which is much slower and is not able to
get nanosecond precision.

Implement the new commpage layout and wall time computation,
using a version check to fallback to the previous code on
older operating systems.

cmd/cgo is special among the build tools because it is (re)built on demand
when needed for a package using cgo, to avoid additional bootstrap logic
elsewhere. (This is in contrast to cmd/compile, cmd/link, and so on, which
must be specially built before even invoking the go command.)

When the go command starts using content-based decisions about staleness,
it is important that the build of cmd/cgo never use -linkmode=external,
because that depends on runtime/cgo, which in turn depends on cmd/cgo.

When variables need to be spilled to the stack, they usually get their
own stack slot. Local variables have a slot allocated if they need one,
and arguments start out on the stack. Before this CL, the debug
information made the assumption that this was always the case, and so
didn't bother storing an actual stack offset during SSA analysis.

There's at least one case where this isn't true: variables that alias
arguments. Since the argument is the source of the variable, the
variable will begin its life on the stack in the argument's stack slot,
not its own. Therefore the debug info needs to track the actual stack
slot for each location entry.

No detectable performance change, despite the O(N) loop in getHomeSlot.

For example, the following type assertion:

    if c, ok := v.(interface {
        Close() error
    }); ok {
    }

Can now be formatted as:

In addition to the obvious formatting change, this also drops
from deps.go any indirect dependencies, so that when you add
a new import to one package, the resulting diff only affects that
one package, not every package that imports that package
directly or indirectly. That makes the file a bit easier to understand,
if you need to debug it or deal with a possible merge conflict.

The code to trim the import lists (but not too much) was more
than I wanted to do in shell, so I rewrote mkdeps in Go.

The shell script is left behind for backwards-compatibility with
people who have learned to run ./mkdeps.bash (or documentation
suggesting the same).
