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.

[DebugInfo] Add DILabel metadata and intrinsic llvm.dbg.label. In order to set breakpoints on labels and list source code around labels, we need collect debug information for labels, i.e., label name, the function label belong, line number in the file, and the address label located. In order to keep these information in LLVM IR and to allow backend to generate debug information correctly. We create a new kind of metadata for labels, DILabel. The format of DILabel is !DILabel(scope: !1, name: "foo", file: !2, line: 3) We hope to keep debug information as much as possible even the code is optimized. So, we create a new kind of intrinsic for label metadata to avoid the metadata is eliminated with basic block. The intrinsic will keep existing if we keep it from optimized out. The format of the intrinsic is llvm.dbg.label(metadata !1) It has only one argument, that is the DILabel metadata. The intrinsic will follow the label immediately. Backend could get the label metadata through the intrinsic's parameter. We also create DIBuilder API for labels to be used by Frontend. Frontend could use createLabel() to allocate DILabel objects, and use insertLabel() to insert llvm.dbg.label intrinsic in LLVM IR.
