Optimize series of ADD_STRING / ADD_CHAR
Convert CAST(IS_BOOL,x) into BOOL(x)
Convert INIT_FCALL_BY_NAME + DO_FCALL_BY_NAME into DO_FCALL
2Convert constant operands to expected types
Convert conditional JMP with constant operands
Optimize static BRK and CONT
3Convert $a = $a + expr into $a += expr
Convert $a++ into ++$a
Optimize series of JMP
4PRINT and ECHO optimization (defunct)
5Block Optimization - most expensive pass
Performs many different optimization patterns based on control flow graph (CFG)
9Optimize register allocation (allows re-usage of temporary variables)
10Remove NOPs
