[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

// RUN: llvm-mc -triple i386-apple-darwin9 %s -filetype=obj -o - | llvm-readobj -s -sd | FileCheck %s
Fix a bug in darwin's 32-bit X86 handling of evaluating fixups. Where it would use a scattered relocation entry but falls back to a normal relocation entry because the FixupOffset is more than 24-bits. The bug is in the X86MachObjectWriter::RecordScatteredRelocation() where it changes reference parameter FixedValue but then returns false to indicate it did not create a scattered relocation entry. The fix is simply to save the original value of the parameter FixedValue at the start of the method and restore it if we are returning false in that case. rdar://15526046 llvm-svn: 196432
