Since FDPIC currently supports arm and thumb-2 modes only, these tests
fail because they enforce an architecture version that doesn't match
these restrictions.
This patch introduces new values for the arm_arch effective-target
(v4t_thumb, v5t_thumb, v5te_thumb, v6_thumb, v6k_thumb, v6z_thumb) as
needed, and adds them to the relevant tests. In addition, it adds
v4t_arm, v5t_arm, v5te_arm, v6_arm, v6k_arm and v6z_arm to avoid
skipping some tests when GCC is configured to generate Thumb code by
default.
It also adds the corresponding non-thumb effective-target to the tests
that were missing it.
The existing v4t, v5t, v5te, v6 v6k and v6z effective-targets now force
-mfloat-abi=softfp since these thumb-1 targets do not support
hard-float anyway.
Finally, the patch removes the special case to detect the presence of
-marm in the flags, since it makes atomic_loaddi tests unsupported:
since the flags in question also include -march, the combination is
supported, while -marm alone is not if GCC is configured to target an
M-profile CPU.
