Compiling the tests with -Wextra results to lots of warnings for unused
parameters. Annotate these cases with the `unused' attribute to avoid
the warnings.
Test that creates MiniDebugInfo-containing binary and then checks if it
can recover the procedure names from its coredump.

The intention in the test cases is to print the "instruction pointer"
value at certain places, and on ARM we will want to get the Program
Counter in these cases. IP is a scratch register, and not very
interesting.
Program test-coredump-unwind was modified to map backing files based on
virtual addresses instead of segment numbers.
The crasher.c is a program that essentially calls some functions and
then writes to invalid address causing a crash. Before that, it detects
which executables are mapped to which virtual addresses and writes this
information to a file suitable for consumption by test-coredump-unwind.
The mapping information is obtained form /proc/self/maps, so currently
it only works on linux.
The test itself is a shell script, which first runs the program and then
runs test-coredump-unwind on the resulting core and address space
map file to check whether the stack trace obtained from the dump roughly
corresponds to what it should look like.
