(alpha_processing,enc}_sse2: quiet signed conv warnings

Browse Source 
_mm_set1_epi8() takes a char argument
_mm_insert_epi16 takes a short argument

from clang-7 integer sanitizer:
implicit conversion from type 'int' of value 255 (32-bit, signed) to
type 'char' changed the value to -1 (8-bit, signed)
implicit conversion from type 'int' of value 33153 (32-bit, signed) to
type 'short' changed the value to -32383 (16-bit, signed)
