ARM: shrink offsets
Move various embedded target structs to the beginnings of their containers ... pretty much the way C++ or Obj-C would for single inheritance. This shrinks code that accesses those embedded structs by letting common offsets use smaller instructions. Sample before/after sizes (on amd64): 17181 312 0 17493 4455 arm920t.o 16810 312 0 17122 42e2 arm920t.o Where the "after" is the smaller number, with this patch over the ones leveraging that embedding knowledge.
