[ELF][PPC64] Fix getRelExpr for R_PPC64_REL16_LO and R_PPC64_REL16_HA The relocations R_PPC64_REL16_LO and R_PPC64_REL16_HA should return R_PC for getRelExpr since they compute #lo(S + A – P) and #ha(S + A – P). Differential Revision: https://reviews.llvm.org/D44648 llvm-svn: 328103

# REQUIRES: ppc
[PPC64] Remove support for ELF V1 ABI in LLD The current support for V1 ABI in LLD is incomplete. This patch removes V1 ABI support and changes the default behavior to V2 ABI, issuing an error when using the V1 ABI. It also updates the testcases to V2 and removes any V1 specific tests. Differential Revision: https://reviews.llvm.org/D46316 llvm-svn: 331529

[PPC][PPC64] Improve some llvm-objdump -d -D tests Various improvement: Some offsets in disassembly are incorrect after several layout adjustment. Fix them. llvm-objdump -D should not be used. -D dumps unrelated non-text sections. Replace them with llvm-objdump -d, llvm-readelf -x, etc Many llvm-objdump -d tests use {{.*}} . Add the option --no-show-raw-insn to avoid check hex bytes. ppc64-long-branch.s does not need a shared object. Delete it. Make ppc64-ifunc.s check 2 ifuncs.
