tcg: Fix iteration step in 32-bit gvec operation
The loop in the 32-bit case of the vector compare operation
was incorrectly incrementing by 8 bytes per iteration instead
of 4 bytes. This caused the function to process only half of
the intended elements.

Fixes: 9622c697d1 (tcg: Add gvec compare with immediate and scalar operand)
