This patch would like to fix one ICE when vector is not enabled
in hook TARGET_FUNCTION_VALUE_REGNO_P implementation. The vector
regno is available if and only if the TARGET_VECTOR is true. The
previous implement missed this condition and then result in ICE
when rv64gc build option without vector.
The below test suite is passed for this patch.
* The rv64gcv fully regression tests.
* The rv64gc fully regression tests.
