vec_roundm: Vector Round toward Negative Infinity

d = vec_roundm(a)

Returns a vector containing the largest representable floating-point integral values less than or equal to the values of the corresponding elements of the given vector.

Note: vec_roundm provides the same functionality as vec_floor, except that vec_roundm would not trigger the IEEE-inexact exception.
