go/ssa/ssautil: add AllPackages method

In go1.10, go/packages falls back to loading all packages
from source but not typechecking function bodies for imports.
The ssautil.Packages function would nonetheless provide
the partially-typed ASTs to the SSA builder, which would crash.
Now Packages only passes syntax trees to the SSA builder for
the initial packages, which are the only ones guaranteed to be
fully typed.

It is impossible to discern whether the caller of Packages intends to
build SSA code for dependencies, as in some clients such as
cmd/callgraph, so we add a new function, AllPackages, that expresses
this intent.

Fixes golang/go#28106
