// Test M-split with neg_lo:[0,0,1] on src2.
//
// Differs from K-split: M-split has no carry, so the original src2's
// modifier applies to BOTH halves (each half has its own M-slice of
// src2). The MATRIX_FMT_FP4 modifiers added by the splitter come BEFORE
// the preserved neg_lo, mirroring how the printer orders them.
