LLVM has TLS_(base_)addr32 for 32-bit TLS addresses in 32-bit mode, and TLS_(base_)addr64 for 64-bit TLS addresses in 64-bit mode. x32 mode wants 32-bit TLS addresses in 64-bit mode, which were not yet handled. This adds TLS_(base_)addrX32 as copies of TLS_(base_)addr64, except that they use tls32(base)addr rather than tls64(base)addr, and then restricts TLS_(base_)addr64 to 64-bit LP64 mode, TLS_(base_)addrX32 to 64-bit ILP32 mode.

This diff by itself results in invalid code due to wrongly using the EBX register; the included test will fail. D16474 <https://reviews.llvm.org/D16474> needs to be applied first, then this on top.
