Bug 827965 - Utilize GetTempRegForIntArg() for callNative calls. (r=sstangl)
Bug 827995. Avoid spending a lot of time in sprintf while assembling for ARM. r=bhackett

During a profile of JS execution on B@G we're spending 10% of the time in
__vfprintf.  At least some of this is in the arm assembler. Since we're not
actually using the strings we're printing we'd be better off not printing them.
