Yeah, this is used as an offset from the TLS base register (tp). GCC doesn't
allow arbitrary offsets for this value, permitting only a value that can be
encoded as an immediate value in the load instruction. I mirrored those limits
(slightly incorrectly) in my patch. Given that llvm can support arbitrary
values as the compiler is happy to use multiple instructions as required, I
think it's probably best to just remove this test instead of introducing an
artificial limit to match gcc's behavior?
