CL 56120043 fixed TLS handling on ARM after the introduction of liblink but left older ARM processors broken. Before liblink, the MRC instruction was replaced with a fallback on older ARMs. CL 56120043 removed that, because the rewrite matched bit patterns on the AWORD pseudo-instruction and could therefore change unrelated AWORDs that happened to match. This CL adds an AMRC instruction to encode both MRC and MCR previously encoded as AWORDs. Then, in liblink, the AMRC instructions are either rewritten to AWORD, or, on goarm < 7, replaced with a branch to the fallback. ./all.bash completes successfully on an ARMv7 with either GOARM=7 or GOARM=5. I have verified that the fallback is indeed present in both runtime.save_gm and runtime.load_gm when GOARM=5 but not when GOARM=7. If all goes well, this should fix the armv5 builders.
