    RISC-V: Bugfix for resolve_overloaded_builtin[PR113420]

    v2:
    Avoid internal ICE for the case below.
    vint8mf8_t test_vle8_v_i8mf8_m(vbool64_t vm, const int32_t *rs1, size_t vl)
{
      return __riscv_vle8(vm, rs1, vl);
    }

    v1:
    Change the hash value of overloaded intrinsic from considering
    all parameter types to:
    1. Encoding vector data type
    2. In order to distinguish vle8_v_i8mf8_m(vbool64_t vm, const int8_t *rs1,
size_t vl)
       and vle8_v_u8mf8_m(vbool64_t vm, const uint8_t *rs1, size_t vl), encode
the pointer type
    3. In order to distinguish vfadd_vv_f32mf2_rm(vfloat32mf2_t vs2,
vfloat32mf2_t vs1, size_t vl)
       and vfadd_vv_f32mf2(vfloat32mf2_t vs2, vfloat32mf2_t vs1, size_t vl),
encode the number of
       parameters. The same goes for the vxrm intrinsics.
