Created new Loop Profile-Based Instrumented Testcases
Created new Loop Profile-Based Instrumented Testcases

Summary:
We started profiling instrumentation testcases in D37014618 (https://github.com/facebook/redex/commit/36a97b06da667a77cba4991ff4e2af849deb429a) but there were no loop testcases
-  Created both For loops and While loops testcases and asserted particular basicblocks were executed
- Created testcases to show that both the for loops and while loops are equivalent leading to the same basicblocks being executed and same output
