The method ArrayList.add() return a boolean, so the bytecode compiler generates
a temp of type promoted_boolean.  Unfortunately, the same temp is used later as
an int.

This problem arises because promoted booleans in the Java VM are really an
integer type, not a boolean type.  It's perfectly legal to store a boolean and
then read an int for the same slot.  So, we need to use int temporaries for
booleans, not promoted_boolean.
