Subject: [PATCH] fixup: SIMD for main loop of a-rate DelayNode

Similar to previous fix to oscillator node. In GCC, an implicit cast to
m128i of the result of mm_cmplt_ps is not valid. In this case, as the
next usage of the return value is already an m128, we just change the
type of the return value to m128 too.
