I mistakenly used a linux-ism in the unit test.. that should be resolved in r185225.

Apologies for the commotion my tests caused.

This is causing buildbot failures:

Log:
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
