Golang 1.9

Fedora 27 brings Golang 1.9, which includes performance improvements, bug fixes, and new features. Most notably, support for type aliasing, parallel compilation, and direct bit manipulation has been added. For a complete list of changes, see upstream change notes at https://tip.golang.org/doc/go1.9.

With this release, support for the ppc64 architecture has been left out from the Fedora Golang packages due to the fact that the ppc64 port of 'GC' is not feature-complete.
