(llvm#81808) This PR introduces the concept of a "trivial function" which applies to a function that only calls other trivial functions and contain literals and expressions that don't result in heap mutations (specifically it does not call deref). This is implemented using ConstStmtVisitor and checking each statement and expression's trivialness.

Such a function's return value is understood to be safe to call any function with. (cherry picked from commit a7982d5)
