done, but such a solution is somewhat inelegant. Moving the relevant
DEFTRANSFORMs to the architecture-specific compiler/* areas is also
possible, but that would duplicate quite a bit of code.

+(defun foo (x y)
+ (< x y))
+
+FOO's IR1 representation is roughly:
+
+(defun foo (x y)
+ (if (< x y)
+ T
+ NIL))
+
+However, if a full call is generated for < (and similarly for other
+predicate functions), then the IF is unnecessary, since the return value
+of (< x y) is already T or NIL.
