Add check for use of specific names for intrinsic functions

[imciner2]

This check uses a lot of the machinery that the comparator check uses, but just applies it to the call nodes to identify the functions.

There is still one point I am not that sure how to handle though - how to do a fix for multiple issues on one line. This can be seen in the example test3, where each violation is getting its own fix instead of both being included in a single fix (since they are all on one line).
