Port the more accurate (and slightly faster) floating point IDCT implementation from jpeg-8a and later.  New research revealed that the SSE/SSE2 floating point IDCT implementation was actually more accurate than the jpeg-6b implementation, not less, which is why its mathematical results have always differed from those of the jpeg-6b implementation.  This patch brings the accuracy of the C code in line with that of the SSE/SSE2 code.
