Change looks good to me. But please fix the new test case as suggested by @nemanjai 
In this new test do you see improvement in register allocation due to IPRA? If test-case does not show any benefit due to IPRA then it is not suitable test for this patch.
Also I hope this patch is also tested with other architecture which have LIT based test-cases for IPRA. It is very unlikely that such test-case will have function with linkage type which return true for isInterposableLinkage() but if such case is there then this change may break such tests.
