 - implement small tuples, there are a lot of places where they are hashed and
   compared
 
-- implement INT_ABS in the JIT, currently jtransform generates a call to an
-  inlined function, which does the trivial branching. However, GCC shows that
-  it can be done branchless in the ASM (as we do for FLOAT_ABS, which is easier
-  because it has an explicit sign bit). GCC generates:
-
-    movq    %rdi, %rdx
-    sarq    $63, %rdx
-    movq    %rdx, %rax
-    xorq    %rdi, %rax
-    subq    %rdx, %rax
-    ret
-
 - ConstantFloat(0.0) should be generated with pxor %xmm, %xmm; instead of a
   movabs.
