[PATCHv3 3/3] contrib: Handle GDB specific test result types

[Andrew Burgess <andrew.burgess@embecosm.com>]

NOTE: I know that this patch needs to go through the GCC list and then
be back-ported to the binutils-gdb repository.  I'm posting it here
for completeness while the other patches in this series are
discussed.  If the general idea is approved for GDB then I'll get this
merged through the GCC route.

When running Dejagnu on GDB we can now (sometimes) see two additional
test result types, these are '# of paths in test names' and '# of
duplicate test names'.

If the test is run in parallel mode (make -j...) then these extra test
results will appear in the individual test summary files, but are not
merged into the final summary file.

Additionally, two new types of test summary line can be printed, these
are 'PATH: ...' and 'DUPLICATE: ....' these lines allow users to
quickly search the test summary to track down where the offending test
names are.  These lines are similarly not merged into the unified
gdb.sum file after a parallel test run.

This commit adds support to the merge scripts to carry over these
extra result types, and the corresponding test status lines.

contrib/ChangeLog:

	* dg-extract-results.py: Handle GDB specific test types.
	* dg-extract-results.sh: Likewise.
