    The compiler was crashing partway through emitting an error for a bad
    self-referential struct type (which refers to one of its own fields
    via an unsafe.Offset expression). Tweak the offset logic to check for
    this class of type error and exit cleanly.

gcc.target/arm/copysign_softfloat_1.c's use of arm_arch_v6t2 in
dg-add-option changes the architecture to -march=armv6t2. Since the test
only requires Thumb-2 capable architecture, we just need to add -mthumb
on the command line since arm_thumb2_ok guarantees by definition that
doing that is enough to select Thumb-2. This fixes warning on the
command line when having -mcpu=cortex-m3 in RUNTESTFLAGS for instance.
