According to the ISA, the zvfhmin sub extension should only contain
convertion insn. Thus, the vfmv insn acts on FP16 should not be
present when only the zvfhmin option is given.
This patch would like to fix it by split the pred_broadcast define_insn
into zvfhmin and zvfh part.
LGTM。

LGTM and ok for gcc 14 as well,
btw an idea is that actually could passed via gpr, I mean fpr->gpr and then
vmv.v.x, but it's not block commend for this pat
Backported to gcc 14 already.
