Copy head (r256279) to stable/10 as part of the 10.0-RELEASE cycle.

Add section .note.GNU-stack for assembly files used by 386 and amd64.

Use __FBSDID() instead of RCSID() in most .S files under lib/msun/i386,
and one under lib/msun/amd64. This avoids adding the identifiers to the
.text section, and moves them to the .comment section instead.

Use, in uncovered part, the END() macro in order to improve debugging.
In this specific case, Valgrind won't get confused when analyzing such
functions.

Fixed some comments added in rev.1.5.

The log message for 1.5 said that some small (one or two ulp) inaccuracies
were fixed, and a comment implied that the critical change is to switch
the rounding mode to to-nearest, with a switch of the precision to
extended at no extra cost. Actually, the errors are very large (ucbtest
finds ones of several hundred ulps), and it is the switch of the
precision that is critical.

Another comment was wrong about NaNs being handled sloppily.

Remove wrappers and other cruft intended to support SVID, mistakes in
C90, and other arcana. Most of these features were never fully
supported or enabled by default.

Ok: bde, stefanf

Removed bogus 'l' suffixes in FP register to register instructions.

$Id$ -> $FreeBSD$

Include <machine/asm.h> instead of kernel-only <machine/asmacros.h>.

Revert $FreeBSD$ to $Id$

Fixed the i87 version of exp(). It returned NaN for args +-Inf. It had
some small (one or two ULP) inaccuracies.

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

Clean up the FP stack before returning. The i387 exp() leaked an FP
register on its first call. Subsequent calls reused the register so
the leak didn't accumulate. Fixes PR 1275.

Do all the includes: <machine/asm.h> -> <machine/asmacros.h>

J.T. Conklin's latest version of the Sun math library.

-- Begin comments from J.T. Conklin:
The most significant improvement is the addition of "float" versions
of the math functions that take float arguments, return floats, and do
all operations in floating point. This doesn't help (performance)
much on the i386, but they are still nice to have.

The float versions were orginally done by Cygnus' Ian Taylor when
fdlibm was integrated into the libm we support for embedded systems.
I gave Ian a copy of my libm as a starting point since I had already
fixed a lot of bugs & problems in Sun's original code. After he was
done, I cleaned it up a bit and integrated the changes back into my
libm.
