[PATCH] Use HALFRAD macro instead of hardcoded value

[Siddhesh Poyarekar <siddhesh at redhat dot com>]

Hi,

I cam across a few instances where 8388608.0 was used directly and
replaced those with the HALFRAD macro.  No regressions on x86_64 and
i686.  OK to commit?  Further, would it be a good idea to consider
such cleanups (replace constants with their equivalent macros) as
obvious?

	* sysdeps/ieee754/dbl-64/mpsqrt.c (__mpsqrt): Use HALFRAD.
	* sysdeps/ieee754/dbl-64/sincos32.c (__mpranred): Likewise.
