This commit adds initial interpreter support for x86_64. I ran all
JRuby benchmarks with this patch and the results were equal to x86_32,
so it looks pretty good.
It seems we still have some problems with UseParallelGC, which might be
the default on 64-bit Darwin, so using UseSerialGC might be a good idea.
Compiler support is yet to come.
Please report all problems you see.
