¶bool stripNonLineTableDebugInfo(llvm::Module& M)

Description

Downgrade the debug info in a module to contain only line table information. In order to convert debug info to what -gline-tables-only would have created, this does the following: 1) Delete all debug intrinsics. 2) Delete all non-CU named metadata debug info nodes. 3) Create new DebugLocs for each instruction. 4) Create a new CU debug info, and similarly for every metadata node that's reachable from the CU debug info. All debug type metadata nodes are unreachable and garbage collected.
