restore EH on x86-vx7r2
x86-vx7r2 needs svr4_dbx_register_map, but the default in i386/i386.h
was dbx_register_map, partially swapping ebp and esp in unwind info.
i386/vxworks.h had a correct overrider, but it was conditional for
vxworks < 7. This patch reenables the overrider unconditionally.
for gcc/ChangeLog
* config/i386/vxworks.h (DBX_REGISTER_NUMBER): Make it
unconditional.
