stage2: tokenizer: require null terminated source
By requiring the source file to be null-terminated, we avoid extra
branching while simplifying the logic at the same time.
Running ast-check on a large zig source file (udivmodti4_test.zig),
master branch compared to this commit:
* 4% faster wall clock
* 7% fewer cache misses
* 1% fewer branches
