------- Additional Comments from Mark Lam <mark.lam at apple.com>
This patch has been tested on:
1. OSX x86_64 running the layout tests
2. The iOS simulator running modified versions of the 2 regression tests served
up by a web server.
3. an ARMv7 iOS build running modified versions of the 2 regression tests
served up by a web server.

Before this fix, the iOS simulator would crash, and the ARMv7 iOS run would
yield the wrong answer for the js/floating-point-denormalized.html test.  With
this fix, the iOS simulator no longer crashes, and the ARMv7 run produces the
correct answer.
