Add (INHIBIT-WARNINGS 3) to various bits of double-double float code.
I checked the notes and they all have to do with either boxing or
generic operations (usually from FLOOR).

This greatly reduces the amount of noise in the compilation logs.

Diff to previous 1.15
o Inhibit warnings for POLY-EVAL and POLY-EVAL-1.
o Add some declarations in various places to get rid of some warnings.
o Rearrange DD-%ASIN to get rid of some warnings.
o Declare the type of DD-%SIN, DD-%COS, and DD-%TAN because cmucl
  doesn't compute the correct return type.

Diff to previous 1.13
compiler/float-tran.lisp:
o Handle signed-zeroes for addition, subtraction, and multiplication
  of double-double floats.  That is, return the correct signed zero
  for the result.
o Try to handle overflow in addition, multiplication, and division by
  returning infinity, if the overflow or divide-by-zero trap is
  disabled.  This is done by looking to see what the corresponding
  double-float operation would return.  This probably needs more work.

code/irrat-dd.lisp:
o Remove the careful-mul stuff from dd-complex-atanh since we handle
  signed zeroes better now during double-double multiplication.

Make DD-%SIN and DD-%TAN return -0w0 when the argument is -0w0.

Revert the previous change to DD-COMPLEX-ATANH.  If z < -1, just call
DD-COMPLEX-ATANH with -0w0 to get the correct value.

Changes since 1.10: +8 -32 lines
Diff to previous 1.10
o Remove some unused constants
o Fix a typo in a docstring.
o Fix DD-COMPLEX-ASIN again:
  - The previous fix for asin(-2) being wrong actually broke the case
    for asin(2).  Revert that.
  - The issue was that in our explicitly handling of the atan(y/0)
    case we didn't take into account the sign y and 0.  Fix that.

Changes since 1.9: +64 -26 lines
Diff to previous 1.9
o Make DD-%ATAN2 handle signed zeroes.  This is needed to get branch
  cuts right for some special functions.
o DD-COMPLEX-ATANH needs to be careful about producing signed zeroes
  in the right spots.  Add a CAREFUL-MUL to make sure a zero of the
  correct sign is produced when needed.  (What other places need such
  care?)

DD-COMPLEX-ATANH was returning the wrong value for real z and z > 1.
It was saying atanh(-2) = .549 - i*pi/2.  The correct answer is
.549 + i*pi/2.

DD-COMPLEX-ASIN was returning the wrong value for real z and z < -1.
It was saying asin(-2) = pi/2+i*1.317.  The correct answer is
-pi/2+i*1.317.

dd-%expm1 was computing the wrong values.  Fix it so that it works.
Only a few spot checks were done, but it seems to be working fine.

Oops.  The argument reduction routine doesn't like negative numbers,
so make dd-%sin, dd-%cos, dd-%tan handle that.

Changes since 1.4: +116 -7 lines
Diff to previous 1.4
Implement accurate arg reduction for the trig functions sin, cos, tan,
using __kernel_rem_pio2.  Use the accurate reduction in dd-%sin,
dd-%cos, dd-%tan.  The original version were renamed dd-%%sin,
dd-%%cos, dd-%%tan because we still need them to evaluate the
functions for small args.

This also has the side effect that we don't signal overflow for
moderately large args (~1w50) anymore.

Oops.  Use 0d0 instead of 0w0 when creating a double-double-float in
dd-cssqs.

compiler/float-tran.lisp:
o Change the following functions to be maybe-inline instead of inline
  so we don't inline them by default unless the user says so by
  specifying (SPACE 0): ADD-DD, MUL-DD-D, MUL-DD, ADD-DD-D, SQR-DD,
  DIV-DD, DIV-DD-D, SQRT-DD

code/irrat-dd.lisp:
o Set (SPACE 0) for these functions so we inline the operations.
  (Should we really inline all of these?)

This large checkin merges the double-double float support to HEAD.
The merge is from the tag "double-double-irrat-end".  The
double-double branch is now obsolete.

The code should build without double-double support (tested on sparc)
as well as build with double-double support (tested also on sparc).
