struct iseq_compile_data_storage: 16 bytes (from 32) overhead
This reduces the iseq_compile_data_storage header from 32 to 16
bytes on 64-bit systems.
pos and size fields cannot exceed 32-bit sizes due to stack size
limits. Using a flexible array for the buffer also saves us 8
bytes of pointer overhead.
