* config/tc-arm.c (s_arm_unwind_save_vfp_armv6): New. Parse
a directive saving VFP registers for ARMv6 or later.
(s_arm_unwind_save): Add parameter arch_v6 and call
s_arm_unwind_save_vfp or s_arm_unwind_save_vfp_armv6 as
appropriate.
(md_pseudo_table): Add entry for new "vsave" directive.
* doc/c-arm.texi: Correct error in example for "save"
directive (fstmdf -> fstmdx). Also document "vsave" directive.
