We don't really need to setup a buffer, print into it and then print it
out to stdout. Simplify the code by directly printing the address (and
symbol name).
This also showed a small error in the output of DW_LLE_startx_length.
It had two unintended trailing dots.

Normal and split dwarf from GNU DebugFission look the same, but should
be treated competely separtely. When having a file with both skeletons
and real compile units only note the secoffsets into the real .debug_loc
in readelf. Otherwise or known_locslistptr will get confused.
Add a testfile that combines an normal -gdwarf-4 object with a
-gsplit-dwarf object. libdw already got this right, but add a
run-varlocs.sh test to make sure.

GNU DebugFission .debug_loc location lists uses the .debug_loc section
in the split dwarf .dwo file. The encoding is a mix of old style DWARF
.debug_loc and new style .debug_loclists.
Add two testcases for the readelf and libdw decoders.

The new DWARF5 .debug_loclists sections are like .debug_rnglists, but
plus locations. For Split Dwarf GCC generates the .debug_loclists fully
in the split .dwo file. Any references to addresses need to be resolved
through the skeleton .debug_addr section.

Also adjust the formatting for the resolved addresses to print them
on separate lines so they nicely line up even when the addresses are
resolved to symbol+offset names. And print the operands starting on
a new line.

Use only 2 spaces for index (there are never 10000, the most seen in the
wild is 64). Adjust re-indenting after GNU_entry_value.

The parallel-tests option was introduced in automake 1.11 and is the
default since automake 1.13. All tests can now be ran in parallel with
make check -j. To enable this all tests are ran in their own temporary
directory so they don't stomp on each others input or output files.
On my machine (4 cores) make check takes ~20 seconds, but now with
make check -j8 takes only ~4 seconds.
ChangeLog:
* configure.ac (AM_INIT_AUTOMAKE): Request parallel-tests.
tests/ChangeLog:
* Makefile.am (installed_TESTS_ENVIRONMENT): Export environment,
remove wrapper.
(TESTS_ENVIRONMENT): Likewise.
(installed_LOG_COMPILER): New variable defining wrapper.
(LOG_COMPILER): Likewise.
* run-*.sh: Fixup location of input and output files.
* test-subr.sh: Create test_dir, pushd to execute test in.
(trap): Remove test_dir.
(testfiles): Use abs_srcdir.
(installed_testrun): Match on abs_builddir or abs_top_builddir.
(self_test_files): Adjust path.
