[PATCH] expansion: Use __trunchfbf2 calls rather than __extendhfbf2 [PR114907]

Hi! The HF and BF modes have the same size/precision and neither is a subset nor superset of the other. So, using either __extendhfbf2 or __trunchfbf2 is weird. The expansion apparently emits __extendhfbf2, but on the libgcc side we apparently have __trunchfbf2 implemented. I think it is easier
