Subject: [arm] Fix vfp_operand_register for VFP HI regs

[arm] Fix vfp_operand_register for VFP HI regs

While looking at PR target/94743 I noticed an ICE when I tried to save
all the FP registers: this was because all HI registers wouldn't match
vfp_register_operand.

gcc/ChangeLog:

	* config/arm/predicates.md (vfp_register_operand): Use VFP_HI_REGS
	instead of VFP_REGS.
