Remove the -fuse-gold-plugin driver option.

* It was redundant with -flto.
* It was confusing since -uAnythingElse is a different option.
* GCC uses -fuse-linker-plugin, so it was not even a compatibility option.

Do not emit duplicate global initializers for template static data members inside namespaces

A quirk of AST representation leads to class template static data member
definitions being visited twice during Clang IRGen resulting in
duplicate (benign) initializers.

Discovered while investigating a possibly-related debug info bug tickled
by the duplicate emission of these members & their associated debug
info.

With thanks to Richard Smith for help investigating, understanding, and
helping with the fix.
