Module::getOrInsertFunction is using C-style vararg instead of
variadic templates.
From a user prospective, it forces the use of an annoying nullptr
to mark the end of the vararg, and there's not type checking on the
arguments. The variadic template is an obvious solution to both
issues.

- Avoid explosive growth of the simplification queue by not queuing
expressions that are alredy in it.
- Add an iteration counter and abort after a sufficiently large number
of iterations (assuming that it's a symptom of an infinite loop).

[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.

Technically, this is actually changes the expression and the original
assert was "wrong", but since the conjunction is with true, it doesn't
matter in this case.
