There is currently only limited support for the "absolute" variants of branch instructions. This patch adds support for the absolute variants of all branches that are currently otherwise supported. This requires adding new fixup types so that the correct variant of relocation type can be selected by the object writer. While the compiler will continue to usually choose the relative branch variants, this will allow the asm parser to fully support the absolute branches, with either immediate (numerical) or symbolic target addresses. No change in code generation intended. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184721 91177308-0d34-0410-b5e6-96231b3b80d8
