Fergus Henderson 0d3388dc3c Warn about obvious instances of infinite recursion: ...

Estimated hours taken: 2

Warn about obvious instances of infinite recursion:
directly recursive calls with the same (or equivalent) input arguments.

compiler/simplify.m:
	Check for new warning.

compiler/det_report.m:
	Add code to output the new warning.

compiler/common.m:
	Export common__vars_are_equivalent, for use by simplify.m.
	Also slightly tidy up the code for that predicate and its callers.
