During tensorize, call Simplify on algorithm and intrinsic definitions before CanonicalSimplify. This will prevent a number of false tensorize mismatches. (#718)

thanks, this we can use this solution for now 

* 1) removed non-determinism from CanonicalSimplify
2) added couple of testcases for CanonicalSimplify

* Use IRDeepCompare instead of comparison of string representation

* Give a warning (instead of fatal error) when two "ComExprEntry"s are equal

* Simplify expressions early on

* fixed lint errors

* 1) Refactored some parts of the unrolling code into their own methods so we can reuse unrolling functionality in other parts of the code. E.g., to explicitly unroll loops with count of 1 when they are programmatically created.
2) Reorder based on top operator before resorting to pointers, which causes non-determinism.

* Fixed lint errors

* Use long long for platforms where long is 32 bits (like windows).

* Make sure scalar chars are signed.

* Re-add NOLINT marker.
