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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@205076 91177308-0d34-0410-b5e6-96231b3b80d8
