[PATCH] D97982: [MC] Introduce NeverAlign fragment type

> Which disables NeverAlign padding (0 bytes)

When do we actually do this computation?  At first glance, MCAssembler::layoutSectionOnce never actually goes back to recompute the size of the NeverAlign padding.

> Which in theory could shrink cmp+jcc to short forms causing an infinite loop, but as long as relaxation only increases instruction sizes, it converges at this point, leaving cmp and jcc in relaxed form.

That seems right.
