mmx/sse2: Use SIMPLE_NEAREST_SOLID_MASK_FAST_PATH for NORMAL repeat

mmx/sse2: Use SIMPLE_NEAREST_SOLID_MASK_FAST_PATH for NORMAL repeat

These two architectures were the only place where
SIMPLE_NEAREST_SOLID_MASK_FAST_PATH was used, and in both cases the
equivalent SIMPLE_NEAREST_SOLID_MASK_FAST_PATH_NORMAL macro was used
immediately afterwards, so including the NORMAL case in the main macro
simplifies the fast path table.

[Pekka: removed extra comma from the end of
 SIMPLE_NEAREST_SOLID_MASK_FAST_PATH]
