[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 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
