Handle common linkage correctly in the gold plugin. This is the plugin version of pr20882. This handles the case of every common symbol being in the IR. We will need some support from gold to handle the case where some symbols are in ELF and some in the IR. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@217458 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
