This patch reverses the edge from DIGlobalVariable to GlobalVariable. This will allow us to more easily preserve debug info metadata when manipulating global variables. Fixes PR30362. A program for upgrading test cases is attached to that bug. Differential Revision: http://reviews.llvm.org/D20147 llvm-svn: 281284
