selftests: improve reported failure locations

This patch introduce a selftest::location struct to wrap up __FILE__
and __LINE__ information (and __FUNCTION__) throughout the selftests,
allowing location information to be passed around.

It updates the helper functions in pretty-print.c to pass through
the precise location of each test, so that if a failure occurs, the
correct line number is printed, rather than a line within a helper
function.

gcc/ChangeLog:
* input.c (test_reading_source_line): Use SELFTEST_LOCATION.
