llvm/test/CodeGen/ARM/2011-01-19-MergedGlobalDbg.ll
Adrian Prantl c271bc0481 Renumber testcase metadata nodes after r290153. 
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
