Show expected vs. actual output on test failure
This patch changes 'make check' output to show sparse output compared to
expected results upon unexpected test failure. For example,
static-forward-decl.c output would look like this if it would not be tagged as
"known to fail":
TEST static forward declaration (static-forward-decl.c)
error: actual error text does not match expected error text.

error: see static-forward-decl.c.error.* for further investigation.
info: test 'static-forward-decl.c' is known to fail
This makes it easier to detect and analyze test breakage.
