The RegisterFile decreases in size (measured in terms of numbers of Registers) as the size of a Register increases. This causes js1_5/Regress/regress-159334.js to fail in 64-bit debug builds. I have a fix, which is to make the RegisterFile on all platforms the same size that it is on 32-bit Release builds.
