selftest: invoke "diff" when ASSERT_STREQ fails
Currently when ASSERT_STREQ or ASSERT_STREQ_AT fail we print
both strings to stderr. However it can be hard to figure out
the problem (e.g. for 1-character differences in long strings).
Extend the output by writing out the strings to tempfiles and
invoking "diff -up" on them when we have such a selftest failure,
to (I hope) simplify debugging.
gcc/ChangeLog:
* selftest.cc (selftest::print_diff): New function.
(selftest::assert_streq): Call it when we have non-equal
non-null strings.
