Kevin Burke bb09f8a29b time: make time.Time print a valid Go string with %#v
Previously calling fmt.Sprintf("%#v", t) on a time.Time value would
yield a result like:

    time.Time{wall:0x0, ext:63724924180, loc:(*time.Location)(nil)}

which does not compile when embedded in a Go program, and does not
tell you what value is represented at a glance.

This change adds a GoString method that returns much more legible
output:

    "time.Date(2009, time.February, 5, 5, 0, 57, 12345600, time.UTC)"

which gives you more information about the time.Time and also can be
usefully embedded in a Go program without additional work.

Update Quote() to hex escape non-ASCII characters (copying logic
from strconv), which makes it safer to embed them in the output of
GoString().

Fixes #39034.
