c641cddb80 AltiVec SIMD implementation of H2V1 and H2V2 plain upsampling (used only when decompressing YCCK images with fast upsampling enabled.)

2517ef72ed Fix bugs in the AltiVec fancy upsampling routines uncovered during additional testing with small image sizes. Since the input width is half the output width, the upsampler should only write a second 16-byte chuck if there are more than 8 input columns left. Additionally, if the width is < 16, then we need to insert a dummy sample (the SSE2 code does this as well, but I neglected to port that portion of the code for some reason.)
