Make pixman-mmx.c compile on x86-32 without optimizationmmxfix
When not optimizing, write _mm_shuffle_pi16() as a statement
expression with inline assembly. That way we avoid
__builtin_ia32_pshufw(), which is only available when compiling with
-msse, while still allowing the non-optimizing gcc to understand that
the second argument is a compile time constant.
