[MC] Convert other MachO tests from macho-dump to llvm-readobj. This commit accomplish two goals: 1) it's a step forward to deprecate macho-dump, now less than 40 tests rely on it. 2) It tests all the MachO specific features introduced in llvm-readobj in the following commits: r246789, r246665, r246474. While the conversion is mostly mechanical (I double-checked all the tests output one by one, but still), a post-commit review is greatly appreciated. llvm-svn: 246904

MC/Mach-O: PCrel relocations weren't using the right base address, they are relative to the fragment address, not its offset. This was masked by the text section normally being at address 0. llvm-svn: 98420

MC tweak symbol difference resolution for non-local symbols. When the non-local symbol in the expression is in the same fragment as the second symbol, the assembler can still evaluate the expression without needing a relocation. For example, on ARM: _foo: ldr lr, (_foo - 4) rdar://10348687 llvm-svn: 148341

Darwin assembler improved relocs when w/o subsections_via_symbols. When the file isn't being built with subsections-via-symbols, symbol differences involving non-local symbols can be resolved more aggressively. Needed for gas compatibility. llvm-svn: 146054
