Align names of compiler passes that detect infinite loops

Rename compiler passes as follows:

  reportLeftRecursion -> reportInfiniteRecursion
  reportInfiniteLoops -> reportInfiniteRepetition

This reflects the fact that both passes detect different ways of causing
the same problem (possible infinite loop when parsing).
