Summary: Our code was expecting that a single (symbol) file contains only one kind of location lists. This is not correct (on non-apple platforms, at least) as a file can compile units with different dwarf versions. This patch moves the deteremination of location list flavour down to the compile unit level, fixing this problem. I have also tried to rougly align the code with the llvm DWARFUnit. Fully matching the API is not possible because of how lldb's DWARFExpression lives separately from the rest of the DWARF code, but this is at least a step in the right direction.
