Refine predicate of operands[2] in divv4hf3 with register_operand.
In the expander, it will emit below insn.
rtx tmp = gen_rtx_VEC_CONCAT (V4SFmode, operands[2],
force_reg (V2SFmode, CONST1_RTX (V2SFmode)));
but *vec_concat<mode> only allow register_operand.
gcc/ChangeLog:
PR target/111745
* config/i386/mmx.md (divv4hf3): Refine predicate of
operands[2] with register_operand.
gcc/testsuite/ChangeLog:
* gcc.target/i386/pr111745.c: New test.
