The previous implementation would cause the graph to contain
many duplicate edges resulting in very large cross products,
so that for some inputs (and random map iteration orders) the
running time of DeleteSyntheticNodes was many minutes---more
than the pointer analysis!
Duplicate edges can arise from an interface call that
dispatches to several different wrapper functions each
wrapping the same declared method.
For example, in the callgraph for go/types, a call to
Object.Pos() dispatches to the synthetic functions (*Type).Pos
and (*Var).Pos, each of which wrap (*object).Pos(). After
DeleteSyntheticNodes, Object.Pos() appeared to call
(*object).Pos() twice.
This change builds the set of all edges and avoids adding
edges already in the set.
Also, document findings.

The old code printed the underlying type; e.g., the type
of time.Millisecond was reported to be int64 rather than
time.Duration.
Testsuite (and corresponding tests) in progress (another CL).

Assuming:
1) package declaration does not exist
2) the Fragment option is set
3) a main function exists
We will assume it is a main package and add the declaration.
This change also sets the Fragment option in goimports.

During block optimization, degenerate conditional logic such
as "false && x" may result in single-predecessor blocks
containing φ-nodes. (Ideally such φ-nodes would be replaced
by their sole operand, but that requires Referrers information
which isn't computed until later.) It is obviously not safe
to fuse such blocks, so now we don't.

GccgoInstallation.InitFromDriver currently parses
the output of gccgo -### to get the gcc version,
target triple, and library paths. At least with
Ubuntu's stock libgo5 package, the search path for
.gox files derived from the version is incorrect.
gccgo uses the DEFAULT_TARGET_VERSION macro when
constructing the search path; this value can be
retrieved from gccgo via the "-dumpversion" flag.
Fixesgolang/go#7772.

The text and images are "baked in" to the godoc executable's
rodata section (~300KB) and are accessible from the godoc
server itself at /lib/godoc/analysis/help.html.
In due course, the page will become visible at
http://golang.org/lib/godoc/analysis/help.html, which will be
the canonical location for this doc (in announcements, etc).
The page is temporarily visible here, for those on the Google corp network:
http://172.26.104.127:7777/lib/godoc/analysis/help.html
Also:
- add link to new doc from source view pages.
- document -analysis flag in cmd/godoc/doc.go
- fix indentation of -analysis flag's help string
