Number literals need to be tokenized

[dsamarin]

Number tokenizing is very long and complex. As of now there isn't a suitable token type for them. The long long needs to be represented with 64-bit integers, which JS does not support natively.

Here's some old code with doesn't tokenize, but goes through the basic steps of tokenizing. It is untested.

We probably won't be able to support long long for a little while, but when we do I would use an object like:

{ size: 64, hi: 0xFF, lo: 0x432 } = 0x000000FF00000432

We'd have to do a few complex things though, like implementation of the Karatsuba algorithm for multiplication.
