[PATCH 06/11] read_cache: use repo_read_index_or_die with different error messages

From

In-Reply-To
<20180516222118.233868-1-sbeller@google.com>

This replaces all patterns of "if (read_cached() < 0) die(some-msg);" with repo_read_index_or_die; this changes the output of the error message.

However as all error messages before were translated, these are for human consumption, so a change in error message is not bad; in fact it makes Git more consistent.
