You can probably merge pcrel-tls-local-dynamic-address-load-reloc.s and pcrel-tls-local-dynamic-value-load-reloc.s.
They are short test cases and they are testing almost exactly the same thing.

I think you can address these nits on review. LGTM.


Consider using --no-show-raw-insn for the objdumps.
We are not checking the instruction encoding.
