• Added support for win64. Exceptions are not working and the stack trace feature is not included yet as it seems not working, since it's not picked up by the debugger(related with the exceptions...).
• Added register aliases (for example for argument registers) to make it easier to write generic code.
• Added support for a plug-able memory allocator for code memory. It enables developers to support freeing of code memory, something the build-in memory manager does not.
• Added jit_function_free(), which allows you to free a compiled jit function with all associated resources. Because of this, the way float constants are stored / initialized has been changed. The 'new' method might consume a few extra bytes but is easier to manage and is cleaner in my opinion.

When you compile with RED_BLACK_DEBUG defined, some windows specific debug statements are included, so currently it's only useful under mingw. It can dump the red-black tree in a format that's compatible with graphviz (http://www.graphviz.org).
