The export data formats (text and binary) emitted by gc in Go 1.7 did
not record the package that "owns" each blank field, even though blank
is an unexported identifier. Before, gcimporter would assume the
package of the export data file owns blank fields within it, even
blank fields reexported from another package. As a result, identical
types would become nonidentical during reexporting.
For bug compatibility with gc, gcimporter now treats blank fields as
if they all belong to the same dummy package, avoiding spurious "can't
assign A to B" errors in tools based on go/types.

BImportData now requires a token.FileSet.
Column numbers are not exported, and are always reported as 1.
Line numbers greater than the limit (currently 64K) are reported as 1.
+ Test that file/line info is correctly preserved for the entire
standard library.

Because the std go/importer's Lookup functionality is incomplete,
clients have no way to create a Go 1.5 types.Package from an io.Reader
reading from gc export data. This package provides a stopgap until
the standard library is complete.
The go/gcimporter package remains unchanged, and uses only the
golang.org/x/tools/go/types package.
