[AIX] enable OrcCAPITest

[shchenz]

Summary

The case was excluded in D101971 because of integrated-as support on AIX.
Now AIX integrated-as improves a lot, we can enable the tests in OrcCAPITest file.

The excluded 4 cases are caused by "LLVM ERROR: Incompatible object format!".
We need to add XCOFF support in RuntimeDyld::loadObject for these 4 cases.

gentle ping...

Since this is just a test case change and it now has bigger test coverage, I will commit this directly if no comments in following week...
