Great. Thanks for your inputs too. 
Yes, I think we can add dependant modules related changes later. I have removed 
them for now.
About the yaml xcoff testing, 
For a basic test case as this one, it works great! I also tried using obj2yaml 
and on a compiled executable for a basic .c test case, and then reversing it 
with yaml2obj and that works fine too. But for the dependant module 
functionality, I might need to check some more, we can check on that in the 
later PRs.

On another note, I have a doubt or maybe I am missing something: I am able to 
run lldb-test successfully on my aix system setup for this new basic xcoff file 
(where I have the entire aix changes along with a reduced xcoff same as in this 
PR). 
But lldb-test does not recognize the object file generated by yaml2obj on a 
linux ppc64 system (where I have only the merged changes and the xcoff changes 
only present in this PR). Is it not supposed to work that way or am I missing 
something?
Any suggestions about what can I try would be great!
