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.

RTL code needs to be consistent about whether it uses the stack
pointer, the frame pointer or the argument pointer to access a
given part of the frame.  alias.c used this to divide accesses
into three independent areas.

The problem in the PR is that we did this for HARD_FRAME_POINTER_REGNUM
even when the register wasn't being used as a frame pointer.  We can't
do that because the frame pointer is then just any old allocatable
register and could certainly point to info accessed through the
argument pointer or stack pointer.
