PowerPC64 toc optimisation for power9
Recognize power9 and a few other insns from older machines. Fixes linker complaints like "toc optimization is not supported for 0xf4090002 instruction". 0xf4090002 is stxsd v0,0(r9) bfd/ * elf64-ppc.c (ok_lo_toc_insn): Add r_type param. Recognize lq,lfq,lxv,lxsd,lxssp,lfdp,stq,stfq,stxv,stxsd,stxssp,stfdp. Don't match lmd and stmd. ld/ * testsuite/ld-powerpc/tocopt7.s, * testsuite/ld-powerpc/tocopt7.out, * testsuite/ld-powerpc/tocopt7.d: New test. * testsuite/ld-powerpc/tocopt8.s, * testsuite/ld-powerpc/tocopt8.d: New test. * testsuite/ld-powerpc/powerpc.exp: Run them.
