* Array put, 32 bits or less. vBB[vCC] <- vAA.
*
* Note: using the usual FETCH/and/shift stuff, this fits in exactly 17
* instructions. We use a pair of FETCH_Bs instead.
*
* for: aput, aput-boolean, aput-byte, aput-char, aput-short
*
* NOTE: this assumes data offset for arrays is the same for all non-wide types.
* If this changes, specialize.
