Fix PR16110: Handle DBG_VALUE in ConnectedVNInfoEqClasses::Distribute(). Now that the LiveDebugVariables pass is running *after* register coalescing, the ConnectedVNInfoEqClasses class needs to deal with DBG_VALUE instructions. This only comes up when rematerialization during coalescing causes the remaining live range of a virtual register to separate into two connected components. llvm-svn: 182592

;
; This test case contains a value that is split into two connected components
; by rematerialization during coalescing. It also contains a DBG_VALUE
; instruction which must be updated during
; ConnectedVNInfoEqClasses::Distribute().
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.
