Also, separate type-checking logic into its own file.
go/packages returns import cycle errors anyway, so we just return them instead.

This changes the analysis code from that which was in unitchecker.go
to that in checker.go, so we can run actions that get facts for dependencies
concurrently.
Adds the rest of the traditional vet suite to the LSP.

This starts hooking up the analysis framework into the LSP. It runs
the Tests analysis (which I think might be the only one that doesn't
need facts or results) and reports its diagnostics if there are
no parse or typecheck failures.
Next step: figure out how to pass through results.

Added a View interface to the source package, which allows for reading
of other files (in the same package or in other packages). We were
already reading files in jump to definition (to handle the lack of
column information in export data), but now we can also read files in
diagnostics, which allows us to determine the end of an identifier so
that we can report ranges in diagnostic messages.

The go/format.Node function fails silently on malformed ASTs, even
though it writes out an invalid tree containing the strings "BadExpr"
and "BadStmt". We fix this by checking for *ast.Bad{Expr,Decl,Stmt}
before running the function. Ultimately, this should be fixed upstream
and just return an error from format.Node.
