//                     ALGORITHM DESCRIPTION - COS()
//                     ---------------------
//
//     1. RANGE REDUCTION
//
//     We perform an initial range reduction from X to r with
//
//          X =~= N * pi/32 + r
//
//     so that |r| <= pi/64 + epsilon. We restrict inputs to those
//     where |N| <= 932560. Beyond this, the range reduction is
//     insufficiently accurate. For extremely small inputs,
//     denormalization can occur internally, impacting performance.
//     This means that the main path is actually only taken for
//     2^-252 <= |X| < 90112.
//
//     To avoid branches, we perform the range reduction to full
//     accuracy each time.
//
//          X - N * (P_1 + P_2 + P_3)
//
//     where P_1 and P_2 are 32-bit numbers (so multiplication by N
//     is exact) and P_3 is a 53-bit number. Together, these
//     approximate pi well enough for all cases in the restricted
//     range.
//
//     The main reduction sequence is:
//
//             y = 32/pi * x
//             N = integer(y)
//     (computed by adding and subtracting off SHIFTER)
//
//             m_1 = N * P_1
//             m_2 = N * P_2
//             r_1 = x - m_1
//             r = r_1 - m_2
//     (this r can be used for most of the calculation)
//
//             c_1 = r_1 - r
//             m_3 = N * P_3
//             c_2 = c_1 - m_2
//             c = c_2 - m_3
//
//     2. MAIN ALGORITHM
//
//     The algorithm uses a table lookup based on B = M * pi / 32
//     where M = N mod 64. The stored values are:
//       sigma             closest power of 2 to cos(B)
//       C_hl              53-bit cos(B) - sigma
//       S_hi + S_lo       2 * 53-bit sin(B)
//
//     The computation is organized as follows:
//
//          sin(B + r + c) = [sin(B) + sigma * r] +
//                           r * (cos(B) - sigma) +
//                           sin(B) * [cos(r + c) - 1] +
//                           cos(B) * [sin(r + c) - r]
//
//     which is approximately:
//
//          [S_hi + sigma * r] +
//          C_hl * r +
//          S_lo + S_hi * [(cos(r) - 1) - r * c] +
//          (C_hl + sigma) * [(sin(r) - r) + c]
//
//     and this is what is actually computed. We separate this sum
//     into four parts:
//
//          hi + med + pols + corr
//
//     where
//
//          hi       = S_hi + sigma r
//          med      = C_hl * r
//          pols     = S_hi * (cos(r) - 1) + (C_hl + sigma) * (sin(r) - r)
//          corr     = S_lo + c * ((C_hl + sigma) - S_hi * r)
//
//     3. POLYNOMIAL
//
//     The polynomial S_hi * (cos(r) - 1) + (C_hl + sigma) *
//     (sin(r) - r) can be rearranged freely, since it is quite
//     small, so we exploit parallelism to the fullest.
//
//          psc4       =   SC_4 * r_1
//          msc4       =   psc4 * r
//          r2         =   r * r
//          msc2       =   SC_2 * r2
//          r4         =   r2 * r2
//          psc3       =   SC_3 + msc4
//          psc1       =   SC_1 + msc2
//          msc3       =   r4 * psc3
//          sincospols =   psc1 + msc3
//          pols       =   sincospols *
//                         <S_hi * r^2 | (C_hl + sigma) * r^3>
//
//     4. CORRECTION TERM
//
//     This is where the "c" component of the range reduction is
//     taken into account; recall that just "r" is used for most of
//     the calculation.
//
//          -c   = m_3 - c_2
//          -d   = S_hi * r - (C_hl + sigma)
//          corr = -c * -d + S_lo
//
//     5. COMPENSATED SUMMATIONS
//
//     The two successive compensated summations add up the high
//     and medium parts, leaving just the low parts to add up at
//     the end.
//
//          rs        =  sigma * r
//          res_int   =  S_hi + rs
//          k_0       =  S_hi - res_int
//          k_2       =  k_0 + rs
//          med       =  C_hl * r
//          res_hi    =  res_int + med
//          k_1       =  res_int - res_hi
//          k_3       =  k_1 + med
//
//     6. FINAL SUMMATION
//
//     We now add up all the small parts:
//
//          res_lo = pols(hi) + pols(lo) + corr + k_1 + k_3
//
//     Now the overall result is just:
//
//          res_hi + res_lo
//
//     7. SMALL ARGUMENTS
//
//     Inputs with |X| < 2^-252 are treated specially as
//     1 - |x|.
//
// Special cases:
//  cos(NaN) = quiet NaN, and raise invalid exception
//  cos(INF) = NaN and raise invalid exception
//  cos(0) = 1
//
