Davide Italiano 591b5a5e72 [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.

Steven Wu 9927206f8c Force the MachO generated for Darwin to have VERSION_MIN load command
On Darwin, it is required to stamp the object file with VERSION_MIN load
command. This commit will provide a VERSRION_MIN load command to the
MachO file that doesn't specify the version itself by inferring from
Target Triple.

Rafael Espindola 844f6b6cfb Relax alignment fragments.
With this we don't need the EffectiveSize field anymore. Without that field
LayoutFragment only updates offsets and we don't need to invalidate the
current fragment when it is relaxed (only the ones following it).

This is also a very small improvement in the accuracy of the layout info as
we now use the after relaxation size immediately.

Rafael Espindola 8911d03504 Patch by David Meyer to avoid a O(N^2) behaviour when relaxing fragments.
Since we now don't update addresses so early, we might relax a bit more than
we need to. This is simillar to the issue in PR8467.

Daniel Dunbar 12f1e32d59 MC/Mach-O: Implement initial support for relaxation.
- The implementation is currently very brain dead and inefficient, but I have a
   clear plan on how to fix it.

 - The good news is, it works and correctly assembles 403.gcc (when built with
   Clang, at '-Os', '-Os -g', and '-O3'). Even better, at '-Os' and '-Os -g',
   the resulting binary is exactly equivalent to that when built with the system
   assembler. So it probably works! :)
