Function opnd_shrink_to_32_bits 

pub unsafe extern "C" fn opnd_shrink_to_32_bits(
    opnd: opnd_t,
) -> opnd_t

Shrinks all 64-bit registers in \p opnd to their 32-bit versions. Also shrinks the size of immediate integers and memory references from OPSZ_8 to OPSZ_4.

\note For 64-bit DR builds only.
