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.

To avoid breaking some tests, D66574, D68664, D67643, and D68668
landed together. However, D68664 introduced an issue now addressed by
D68839, with which these are now all relanding.
