Jian Cai c97feb8b52 [MC] Recalculate fragment offsets after relaxation
Summary:
The current relaxation implementation is not correctly adjusting the
size and offsets of fragements in one section based on changes in size
of another if the layout order of the two happened to be such that the
former was visited before the later. Therefore, we need to invalidate
the fragments in all sections after each iteration of relaxation, and
possibly further relax some of them in the next ieration. This fixes
PR#45190.
