gold plugin: Handle gold selecting a linkonce GV when a weak is present. The plugin API doesn't have the notion of linkonce, only weak. It is up to the plugin to figure out if a symbol used only for the symbol table can be dropped. In particular, it has to avoid dropping a linkonce_odr selected by gold if there is also a weak_odr. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@219188 91177308-0d34-0410-b5e6-96231b3b80d8

[gold] Consolidate the gold plugin options and actually search for a gold binary explicitly. Substitute this binary into the tests rather than just directly executing the 'ld' binary. This should allow folks to inject a cross compiling gold binary, or in my case to use a gold binary built and installed somewhere other than /usr/bin/ld. It should also allow the tests to find 'ld.gold' so that things work even if gold isn't the default on the system. I've only stubbed out support in the makefile to preserve the existing behavior with none of the fancy logic. If someone else wants to add logic here, they're welcome to do so. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@229251 91177308-0d34-0410-b5e6-96231b3b80d8
