Disable promotion of custom-layout structs for legacy backend.

These kinds of structs--particularly structs with holes--are not handled
correctly by argument morphing on ARM.

Promotion of these kinds of structs was already disabled for the x86
legacy backend; this change disables the optimization  for all legacy
backend targets.

Fixes #12909.
