Returning a void is not allowed by the spec. Just return instead.

Intra Block Copy relies on reconstructed pixels from the current frame.
We skip IBC during the inter prediction stage and handle it during the reconstruction stage.
These arrays are currently accessed via uint16_t* pointers
although nothing guarantees their alignment. Furthermore,
this is problematic wrt the effective-type rules.
Fix this by using a union of arrays of uint8_t and uint16_t.

VVC specifies << as arithmetic left shift, i.e. x << y is equivalent to
x * pow2(y). C's << on the other hand has UB if x is negative. This
patch removes all UB resulting from this, mostly by replacing x << y
with x * (1 << y), but there are also a couple places where the OOP was
changed instead.
