This reverts commit 289920 (again). I forgot to implement a Bitcode upgrade for the case where a DIGlobalVariable has not DIExpression. Unfortunately it is not possible to safely upgrade these variables without adding a flag to the bitcode record indicating which version they are. My plan of record is to roll the planned follow-up patch that adds a unit: field to DIGlobalVariable into this patch before recomitting. This way we only need one Bitcode upgrade for both changes (with a version flag in the bitcode record to safely distinguish the record formats). Sorry for the churn! llvm-svn: 289982
