Add RelocVisitor support for MachO This commit adds partial support for MachO relocations to RelocVisitor. A simple test case is added to show that relocations are indeed being applied and that using llvm-dwarfdump on MachO files no longer errors. Correctness is not yet tested, due to an unrelated bug in DebugInfo, which will be fixed with appropriate testcase in a followup commit. Differential Revision: http://reviews.llvm.org/D8148 llvm-svn: 238663

[DWARF] Fix a bug in line info handling This fixes a bug in the line info handling in the dwarf code, based on a problem I when implementing RelocVisitor support for MachO. Since addr+size will give the first address past the end of the function, we need to back up one line table entry. Fix this by looking up the end_addr-1, which is the last address in the range. Note that this also removes a duplicate output from the llvm-rtdyld line table dump. The relevant line is the end_sequence one in the line table and has an offset of the first address part the end of the range and hence should not be included. Also factor out the common functionality into a separate function. This comes up on MachO much more than on ELF, since MachO doesn't store the symbol size separately, hence making said situation always occur.
