Prepare for radical source tree reorganization.zack/build-layout-experiment

All top-level files and directories are moved into a temporary storage
directory, REORG.TODO, except for files that will certainly still
exist in their current form at top level when we're done (COPYING,
COPYING.LIB, LICENSES, NEWS, README), all old ChangeLog files (which
are moved to the new directory OldChangeLogs, instead), and the
generated file INSTALL (which is just deleted; in the new order, there
will be no generated files checked into version control).

-/* double [fp1] sqrt (double x [fp1])
-   Power4 (ISA V2.0) and above implement sqrt in hardware (not optional).
-   The fsqrt instruction generates the correct value for all inputs and
-   sets the appropriate floating point exceptions.  Extended checking is
-   only needed to set errno (via __kernel_standard) if the input value
-   is negative.
-
-   So compare the input value against the absolute value of itself.
-   This will compare equal unless the value is negative (EDOM) or a NAN,
-   in which case we branch to the extend wrapper.  If equal we can return
-   the result directly.
-
-   This part of the function looks like a leaf routine,  so no need to
-   stack a frame or execute prologue/epilogue code. It is safe to
-   branch directly to w_sqrt as long as the input value (f1) is
-   preserved. Putting the sqrt result into f2 (float parameter 2)
-   allows passing both the input value and sqrt result into the extended
-   wrapper so there is no need to recompute.
-
-   This tactic avoids the overhead of stacking a frame for the normal
-   (non-error) case.  Until gcc supports prologue shrink-wrapping
-   this is the best we can do.  */
