DejaGNU changed its header line from "Test Run By" to "Test run by"
around 2016.  This patch makes it so that both alternatives are
correcly detected.

contrib/ChangeLog:

	* dg-extract-results.py: Make the test_run regex case
	insensitive.

    The header of the python version looked like:
    Target is ...
    Host   is ...
    The header of the bash version looked like:
    Test run by ... on ...
    Target is ...

    After this change both headers look like:
    Test run by ... on ...
    Target is ...
    Host   is ...

    The order of the tests is not the same but since dg-cmp-results.sh it
    does not matter much.

contrib/ChangeLog:

	* dg-extract-results.py: Print the "Test run" line.
	* dg-extract-results.sh: Print the "Host" line.

This commit is for the benefit of GDB, but as the binutils-gdb
repository shares the contrib/ directory with gcc, this commit must
first be applied to gcc then copied back to binutils-gdb.

This commit extends the two scripts contrib/dg-extract-results.{py,sh}
to handle some new, GDB specific test result types.  These test
results types should never appear in GCC, or any other tool that
shares the contrib/ directly, so this change should be harmless.

In this patch series:
  https://sourceware.org/pipermail/gdb-patches/2020-April/167847.html
changes were made in GDB's use of Dejagnu so that two additional
conditions could be detected, these are:

  1. Test names that contain either the build or source paths.  Such
  test names make it difficult to compare the results of two test runs
  of GDB from two different directories, and

  2. Duplicate test names.  Duplicates make it difficult to track down
  exactly which test has failed.

When running Dejagnu on GDB we can now (sometimes) see two additional
test result types matching the above conditions, 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, within the summary file there are now two new types of
test summary line, these are 'PATH: ...' and 'DUPLICATE: ...', these
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 extends the dg-extract-results.* scripts to calculate the
totals for the two new result types, and to copy the new test summary
lines into the unified summary file.

contrib/ChangeLog:

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

Extend dg-extract-results.sh and dg-extract-results.py to support the
KPASS test result status.  This is required by GDB which uses a copy
of the dg-extract-results.{sh,py} scripts that it tries to keep in
sync with GCC.

ChangeLog:

        * contrib/dg-extract-results.sh: Add support for KPASS.
        * contrib/dg-extract-results.py: Likewise.

	* dg-extract-results.sh: Only handle WARNING: program timed out
	lines specially in "$MODE" == "sum".  Restore previous behavior
	for "$MODE" != "sum".  Clear has_timeout and timeout_cnt if in
	a different variant or curfile is empty.
	* dg-extract-results.py: Fix a typo.
