This patch renumbers the metadata nodes in debug info testcases after https://reviews.llvm.org/D26769. This is a separate patch because it causes so much churn. This was implemented with a python script that pipes the testcases through llvm-as - | llvm-dis - and then goes through the original and new output side-by side to insert all comments at a close-enough location. Differential Revision: https://reviews.llvm.org/D27765 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@290292 91177308-0d34-0410-b5e6-96231b3b80d8
