This allows some duplicate comparisons to be omitted, resulting in a size
reduction and performance increase.

64-bit machines, giving a small size reduction and speed boost.

changed.

do not read it. This is a harmless OSSFuzz/ASAN found problem.

perform any necessary text encoding conversions and check for oversize
strings and BLOBs. Thus those checks can be done where they are most
efficient and avoided in cases like OP_Function where they are more
expensive.
