Title: M0 double precision

Update the perl m0 interpreter to use double precision floating point number.

Also, update several of the tests that were using sub_n on integer values. This worked before since both N and I registers were the same size (4 bytes) but now that they are different sizes, these tests fail.

Integer constants should only be operated on with integer ops.
