I implemented this in a different way.  I moved the functions from
arm.cc into reloc.h.  I put them in a template class Bits and gave them
slightly different names.  Please update your sources as per the arm.cc
patch below, now committed to mainline.

	* reloc.h (Bits): New class with static functions, copied from
	namespace utils in arm.cc.
	* arm.cc (namespace utils): Remove.  Rewrite all uses to use Bits
	instead.
