Recommit r298282 with fixes for memory allocation/deallocation

[Hexagon] Recognize polynomial-modulo loop idiom again

Regain the ability to recognize loops calculating polynomial modulo
operation. This ability has been lost due to some changes in the
preceding optimizations. Add code to preprocess the IR to a form
that the pattern matching code can recognize.
