Anyone interested in making this work should have two options here. (1) turn on ASSEMBLER_WX_EXCLUSIVE. This may not be well tested lately in ToT, but will stop allocating WX memory. (2) Set the flags in Platform.h to compile in both the JIT & the interpreter. If the JIT buffer allocation fails it should automatically fall back to use the JIT.
