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
