Rafael Espindola 2bf6afc277 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.

// This is a case where llvm-mc computes a better layout than Darwin 'as'. This
// issue is that after the first jmp slides, the .align size must be
// recomputed -- otherwise the second jump will appear to be out-of-range for a
