JVM_IR: Do not materialize negated boolean for branches.

Instead, flip the branch targets. This generates java byte code
such as:

   L2
    IFNE L3
    ALOAD 0
    INVOKEVIRTUAL A.getX ()F
    GOTO L4
   L3

instead of:

   L2
    IFNE L3
    ICONST_1
    GOTO L4
   L3
    ICONST_0
   L4
    IFEQ L5
    ALOAD 0
    INVOKEVIRTUAL A.getX ()F
    GOTO L6
   L5
