Summary: Reverse Loop optimization

Initial Comment:
Taken from document:

SDCC:
"conditions where loop reversing is not done :


1-The <for body> does not contain ``continue'' or 'break''. 
2-All goto's are contained within the loop. 
3-No function calls within the loop. 
4-The loop control variable <sym> is not assigned any 
value within the loop 
5-The loop control variable does NOT participate in any 
arithmetic operation within the loop. 
6-There are NO switch statements in the loop."

Farshad:
you must add the following condition to the code 
generator to avoid using loop reversing when:

7-The loop control variable is not used as an index to an 
array :))
