-; Check subtraction of a variable.
-; - CHECK is for the main loop.
-; - CHECK-SHIFT1 makes sure that the negated shift count used by the second
-;   RLL is set up correctly.  The negation is independent of the NILL and L
-;   tested in CHECK.
-; - CHECK-SHIFT2 makes sure that %b is shifted into the high part of the word
-;   before being used.  This shift is independent of the other loop prologue
-;   instructions.
