[m-dev.] trivial diff: delete unused ml_translate_builtin

[Fergus Henderson]

Estimated hours taken: 0.1

compiler/ml_call_gen.m:
	Delete (for the second time) some unused code that trd seems
	to have accidentally re-added, probably due to a mistake when
	merging my changes with his.

-	% Given a module name, a predicate name, a proc_id and a list of
-	% the lvals for the arguments, find out if that procedure of that
-	% predicate is an inline builtin. If yes, the last two arguments
-	% return two things:
-	%
-	% - an rval to execute as a test if the builtin is semidet; or
-	%
-	% - an rval to assign to an lval if the builtin is det.
-	%
-	% Exactly one of these will be present.
-	%
-	% XXX this is not great interface design -
-	% better to return a discriminated union than
-	% returning two maybes.  But I kept it this way so that
-	% the code stays similar to code_util__translate_builtin.
