Adding tests for DebugIR pass - lit tests verify that each line of input LLVM IR gets a !dbg node and a corresponding entry of metadata that contains the line number - unit tests verify that DebugIR works as advertised in the interface - refactored some useful IR generation functionality from the MCJIT unit tests so it can be reused git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@185212 91177308-0d34-0410-b5e6-96231b3b80d8
