The compiler only generates the new indexed export format, and any support for the old binary export format has been removed.

We can eliminate the support from go/importer as well.

(Before we do, double-check that the latest version of that code is ported to x/tools where it needs to survive for another 3 release cycles - until 1.14.)

We can't fix this bug until we've done #28260, otherwise there will be no export data format that go/types can both read and write.

Moving to 1.13 - depends on #28260.

#28260 has been fixed.

Verify that we don't need the binary export format anywhere before taking action on this.

This issue is currently labeled as early-in-cycle for Go 1.15. That time is now, so friendly ping. If it no longer needs to be done early in cycle, that label can be removed.

This broke current tests in x/tools, so it either needs to be reverted or those tests need to be updated or removed ASAP.
