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.
