All calling conventions for native methods are #defines

We support two types of garbage collectors
1. Precise Garbage Collector
2. Conservative Garbage Collector

CALLXX => CALL, no of additional parameters other than the name, no of parameters for garbage collection
for e.g. 
CALL11(x, y, y)
call, 1= number of parameters i.e. y,  1= No of parameters to be garbage collected i.e. y
