Fix an annoying little bug I found while debugging another LTO issue. Gold requires the -plugin to come before any -plugin-opt options, we were passing them the other way around. With this one can run (for example): clang -o foo foo.c -O4 -Wl,-plugin-opt=generate-api-file llvm-svn: 154357

Refactor the x86 CPU name logic in the driver and pass -march and -mcpu flag information down from the Clang driver into the Gold linker plugin for LTO. This allows specifying -march on the linker commandline and should hopefully have it pass all the way through to the LTO optimizer. Fixes PR14697. llvm-svn: 172354
