Joel E. Denny a871d949f1 [lit] Clean up internal diff's encoding handling
As suggested by rnk at D67643#1673043, instead of reading files
multiple times until an appropriate encoding is found, read them once
as binary, and then try to decode what was read.

For Python >= 3.5, don't fail when attempting to decode the
`diff_bytes` output in order to print it.

Avoid failures for Python 2.7 used on some Windows bots by
transforming diff output with `lit.util.to_string` before writing it
to stdout.

Finally, add some tests for encoding handling.
