tests: Add new varlocs test for dwarf_getlocation* functions.
This tests the new dwarf_getlocations, dwarf_getlocation_attr and
dwarf_getlocation_die functions. But it is also an example of how
to handle location expressions and which libdw functions can be
used to access all information required to interpret each DW_OP.
It might make sense to extend this test/example into a program
that verifies various properties of DWARF expressions.
