Add an implementation of name= for go list. It will be used to
implement goimports and godoc-like lookups by package name.
Imported a copy of the semver package from the stdlib to do version
comparison, and tweaked the gopathwalk API to include a hint about what
kind of source directory is being traversed.
Note that the tests, despite my best efforts, are not hermetic: go list
insists on doing version lookups in situations where it seems to me like
it shouldn't need to.
I think this implementation is ready for serious use. The one thing I'm
nervous about is that it currently does a substring match when looking
for a package name, so if you look up a package named "a" you will get
a huge number of results. This matches goimports' behavior but I don't
know if it's suitable for general use.

Guide to changes:
- The -printfuncs flag is renamed -printf.funcs.
It no longer supports "pkg.T.f" form, requiring instead
"(dir/pkg.T).f" or "(*dir/pkg.T).f".
The legacy ":%d" suffix is no longer supported.
- (*testing.T).Errorf and friends are removed from the isPrint map
because they are discovered by induction while analyzing package
"testing".
- localPrintfLike map operations are replaced by the Fact mechanism.
- The go/types representation is used instead of strings/ast.Nodes in
various places. For example:
pkgpath, name string -> *types.Func (to identify a function)
format, args *ast.Field -> *types.Var (to identify format/args params)
This was required to fix a latent bug in maybePrintfWrapper's
handling of format string parameters` declared using "factored"
syntax, such as: func f(foo, format string, args...interface{}).
See L253 of the original testdata file for a testcase that ensured
the buggy (?) behavior.
- func printfLike is removed as it was deadcode.
- isFormatter is rewritten to avoid a global variable.
- "if verbose { warn }" is replaced by "if false { report }" for now.
- recursive stringer is rewritten more simply in term of go/types.

Replace the repeated Process/err check/output block with a test helper

from disk rather than the argument to Process; this is mostly me being
selfish: go/packages doesn't support creating new packages with overlays

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.

We plan to change goimports to use go/packages, which requires changing
its internal design. Having tests use the external interface makes those
changes easier. After this change almost all testing is through Process.
Broadly speaking, the changes are:
- Switch to subtests wherever possible. This involved making up many
names, which I hope are accurate.
- Convert tests that used findImport directly to use Process instead.
This often made them slightly larger but not unduly IMO.
- Replace simple tests with entries in the giant table at the top.
- Remove uses of custom goroots, which are troublesome for
go/packages' use of the go command. Almost none of them were actually
necessary. I left one in TestGoRootPrefixOfGoPath; I'm not sure how
to handle it yet.

The typechecker's Sizes function is not currently set correctly.
The correct answer requires information known only to the build
system's query tool (go list, blaze query, etc), and we need to
add a mechanism for it to return this information.
In the meantime, we use this simple workaround: if the GOARCH
environment variable is set, we use that to determine sizes according
to the conventions of gc. Otherwise, we use the architecture for which
the application was compiled. Both could easily be incorrect, but this
is nonetheless progress.
This change should fix the tests of go/analysis/passes/shift,
which are currently broken for GOARCH=386 because the analysistest
