Added new diagnostic for non-linear conditionals
The new diagnostics is triggered if a conditional is used that may not be transformed into linear code by the later by the if conversion. The new diagnostic is emitted if a conditional may contain an unsafe expression or is contained within another conditional, logical and or logical or expression. An expression is unsafe if it contains a call, changes memory or if its evaluation leads to undefined behavior, for example division and modulo. Also fixes a small typo in a comment in Cutil.
