[BUG] When printing the same SIMD vector with multiple print args, SIMD vector values are different

[VMois]

Bug description

Values are different when printing SIMD vector as a single argument in print vs second argument.

Steps to reproduce

alias simd_width = 16

fn main():
    print(SIMD[DType.uint8, simd_width](0, 0x0f))
    print("arg 1", SIMD[DType.uint8, simd_width](0, 0x0f))
    print("arg 1", "arg 2", SIMD[DType.uint8, simd_width](0, 0x0f))

Output:

[0, 15, 0, 15, 0, 15, 0, 15, 0, 15, 0, 15, 0, 15, 0, 15]
arg 1 [0, 15, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0]
arg 1 arg 2 [0, 15, 0, 15, 0, 15, 0, 15, 0, 15, 0, 15, 0, 15, 0, 15]

The correct output should be a second print (arg1 only).

I can't reproduce with mojo 2024.4.1618 (37a3e965), nightly

You didn't provide enough values for vector initialisation so I think it's suppose to be UB.
