Roll back my two recent changes. Stringer is now very slow again,
but works in most use cases.
My git foo is insufficient to do this as a revert, but it is a by-hand
reversion of CLs

The feature has been requested but, like build tags in general,
only works in a directory, not when files are specified explicitly.
Unlike the build tools, report when the feature is misused like this
to avoid confusion.

Revert "cmd/stringer: use source importer when available"
This reverts CL 40403.
The idea is to avoid type-checking and use just parsing, which should be
enough for stringer.
Separately reopening golang/go#10249 because the original change closed that issue,
but the change is itself causing other problems as described in the discussion
at golang/go#25650.
This reversion restores the old behavior of stringer and will be followed
with other fixes if they can be worked out.

This means that running stringer should always
have the intended effect, without having to
go install the package first, which was a common
source of confusion.
The source importer is marginally slower,
but stringer is run infrequently,
and we're only typechecking one package (and fmt),
not an entire tree, as vet does.
