The full multiply intrinsics are not included for EEW=64 in Zve64*.
They require the V extension to be enabled.

This commit improves diagnostic message from

  <source>:4:10: error: call to undeclared function '__riscv_vsmul_vv_i64m1';
      4 |   return __riscv_vsmul_vv_i64m1(op1, op2, __RISCV_VXRM_RNU, vl);

to

  test.c:5:10: error: builtin requires: v
      5 |   return __riscv_vsmul_vv_i64m1(op1, op2, __RISCV_VXRM_RNU, vl);
