    RISC-V: Add zhinx/zhinxmin testcases.
    
    Test zhinx/zhinxmin support, same like with zfh/zfhmin testcases
    but use gprs and don't use fmv instruction.
    
    gcc/testsuite/ChangeLog:
    
            * gcc.target/riscv/_Float16-zhinx-1.c: New test.
            * gcc.target/riscv/_Float16-zhinx-2.c: New test.
            * gcc.target/riscv/_Float16-zhinx-3.c: New test.
            * gcc.target/riscv/_Float16-zhinxmin-1.c: New test.
            * gcc.target/riscv/_Float16-zhinxmin-2.c: New test.
            * gcc.target/riscv/_Float16-zhinxmin-3.c: New test.
