[PATCH] D29349: Fix the bitcode upgrade for DIGlobalVariable in a DIImportedEntity context.

[Adrian Prantl via Phabricator via llvm-commits]

aprantl created this revision.

The bitcode upgrade for DIGlobalVariable unconditionally wrapped DIGlobalVariables in a DIGlobalVariableExpression. When a DIGlobalVariable is referenced by a DIImportedEntity, however, this is wrong. This patch fixes the bitcode upgrade by deferring the creation of DIGlobalVariableExpressions until we know the context of the DIGlobalVariable.
