review TREE_NODE_SZ_SMALL against TREE_NODE_SZ_LARGE

[sandreenko]

max(sizeof(GenTreeIntCon), sizeof(GenTreeLclFld));

GenTreeIntCon has 3 pointer size values

// In debug, on some platforms (e.g., when LATE_DISASM is defined), GenTreeIntCon is bigger than GenTreeLclFld.

GenTreeIntCon doesn't depend on LATE_DISASM

Print all structs and their sizes.
