Remove the unused leftovers of the 4.4BSD libm, which was only used

on non-IEEE platforms.  Since the VAX port was discontinued, all
our remaining architectures use IEEE floating point, as will any
future ones.

-/* ACOSH(X)
- * RETURN THE INVERSE HYPERBOLIC COSINE OF X
- * DOUBLE PRECISION (VAX D FORMAT 56 BITS, IEEE DOUBLE 53 BITS)
- * CODED IN C BY K.C. NG, 2/16/85;
- * REVISED BY K.C. NG on 3/6/85, 3/24/85, 4/16/85, 8/17/85.

- * Required system supported functions :
- *	sqrt(x)
- *
- * Required kernel function:
- *	log1p(x) 		...return log(1+x)
- *
- * Method :
- *	Based on
- *		acosh(x) = log [ x + sqrt(x*x-1) ]
- *	we have
- *		acosh(x) := log1p(x)+ln2,	if (x > 1.0E20); else
- *		acosh(x) := log1p( sqrt(x-1) * (sqrt(x-1) + sqrt(x+1)) ) .
- *	These formulae avoid the over/underflow complication.
- *
- * Special cases:
- *	acosh(x) is NaN with signal if x<1.
- *	acosh(NaN) is NaN without signal.
- *
- * Accuracy:
- *	acosh(x) returns the exact inverse hyperbolic cosine of x nearly
- *	rounded. In a test run with 512,000 random arguments on a VAX, the
- *	maximum observed error was 3.30 ulps (units of the last place) at
- *	x=1.0070493753568216 .
- *
- * Constants:
- * The hexadecimal values are the intended ones for the following constants.
- * The decimal values may be used, provided that the compiler will convert
- * from decimal to binary accurately enough to produce the hexadecimal values
- * shown.
