This seems to be a vectorizer bug.
vectorizable_conversion is called on

vectype_in is __vector int (V4SFmode) and modifier is NONE.
targetm.vectorize.builtin_conversion (FLOAT_EXPR, <__vector int>) returns
__builtin_altivec_vcfsx, which converts V4SI argument to V4SF. But what
vect_get_vec_defs actually returns in vec_oprnds0 is not V4SI, but V4SF.
