Have you tested USE(JSVALUE32)? – we shouldn't break this.

One thought that might help a little on x86-64, you could plant these
values:...
> +static const double oneConstant = 1.0;
> +static const double negativeHalfConstant = -0.5;
...somewhere in the JIT code buffers, then these could be loaded with a
PC-relative memory access.
