This can become a problem in huge files with lots of TLS accesses, as it may slowly move branch targets out of the range computed by the branch relaxation pass. Fixes PR24234 https://llvm.org/bugs/show_bug.cgi?id=24234 Differential Revision: https://reviews.llvm.org/D22870 This fixes "error in backend: fixup value out of range" when compiling the misc/talkfilters port for AArch64.
