Completely rewrite ELFObjectWriter::RecordRelocation. I started trying to fix a small issue, but this code has seen a small fix too many. The old code was fairly convoluted. Some of the issues it had: * It failed to check if a symbol difference was in the some section when converting a relocation to pcrel. * It failed to check if the relocation was already pcrel. * The pcrel value computation was wrong in some cases (relocation-pc.s) * It was missing quiet a few cases where it should not convert symbol relocations to section relocations, leaving the backends to patch it up. * It would not propagate the fact that it had changed a relocation to pcrel, requiring a quiet nasty work around in ARM. * It was missing comments. llvm-svn: 205076 2014-03-29 14:26:49 +08:00			`// RUN: not llvm-mc -filetype=obj -triple x86_64-pc-linux-gnu %s -o /dev/null \`
