Use 4-tap filter in 2D compound Neon convolution for w <= 4

4-tap filters are used for horizontal convolutions that operate on
blocks of width <= 4. (Except when using the 12-tap MULTITAP_SHARP2
filter.) This patch changes the horizontal pass of 2D compound Neon
convolution to use a true 4-tap filter for blocks of width <= 4,
instead of using a filter 0-padded to 8 taps.
