Load*Field and Init*Field IL instructions are fused into load instructions with 'calls_initializer' flag. A new, more powerful elimination of lazy initializer calls uses data flow analysis and load forwarding (place numbering). In addition to improved elimination of initializer calls, fusing instructions avoids extra load after field is already loaded for lazy initialization check.
