Fix static relocation model for PowerPC64

Browse source 
We now also use `should_assume_dso_local()` for declarations and port two
additional cases from clang:
- Exclude PPC64 [1]
- Exclude thread-local variables [2]

[1]: 033138ea45/clang/lib/CodeGen/CodeGenModule.cpp (L1038-L1040)
[2]: 033138ea45/clang/lib/CodeGen/CodeGenModule.cpp (L1048-L1050)
