Change the size specifiers to match the actual element sizes
of the data.  This makes no practical difference with strict
alignment checking disabled (the default) other than somewhat
documenting the code.  With strict alignment checking on, it
avoids trapping the unaligned loads.

Converting the double to float for lrintf() loses precision when
the value is not exactly representable as a single-precision float.
Apart from being inaccurate, this causes discrepancies in some
configurations due to differences in rounding.

Note that the changed timestamp in the vc1-ism test is a bogus,
made-up value.

Code mostly inspired by vp8's MC, however:
- its MMX2 horizontal filter is worse because it can't take advantage of
  the coefficient redundancy
- that same coefficient redundancy allows better code for non-SSSE3 versions

Benchmark (rounded to tens of unit):
        V8x8  H8x8  2D8x8  V16x16  H16x16  2D16x16
C       445    358   985    1785    1559    3280
MMX*    219    271   478     714     929    1443
SSE2    131    158   294     425     515     892
SSSE3   120    122   248     387     390     763

End result is overall around a 15% speedup for SSSE3 version (on 6 sequences);
all loop filter functions now take around 55% of decoding time, while luma MC
dsp functions are around 6%, chroma ones are 1.3% and biweight around 2.3%.

The vertically interpolating variants of these functions read
ahead one line to optimise the loop.  On the last line processed,
this might be outside the buffer.  Fix these invalid reads by
processing the last line outside the loop.
