New Revision: 46167

URL: http://llvm.org/viewvc/llvm-project?rev=46167&view=rev
Log:
Merge from mainline.
Revert the part of 45848 that treated weak globals
as weak globals rather than commons.  While not wrong,
this change tickled a latent bug in Darwin's strip,
so revert it for now as a workaround.
