Robert Griesemer a1aafd8b28 cmd/compile: generate interface method expression wrapper for error.Error
A prior optimization (https://golang.org/cl/106175) removed the
generation of unnecessary method expression wrappers, but also
eliminated the generation of the wrapper for error.Error which
was still required.

Special-case error type in the optimization.

Fixes #29304.
