      gdb/testsuite: Disable path and duplicate checks when parallel testing

Now that this commit has landed:

  commit c959562d9ba0b2eaf240c601b2c2fd49c42c1f2f
  Date:   Fri May 15 11:23:59 2020 +0100

      contrib: Update dg-extract-results.* from gcc

We can now make use of the mechanism for detecting paths in test names
and duplicate test names, even when we run tests in parallel.

gdb/testsuite/ChangeLog:

	* lib/check-test-names.exp: Remove code that prevents this file
	loading when tests are run in parallel.

 # name.  When a test includes the path in its test name it is harder
 # to compare results between two runs of GDB from different trees.
 
-# This is a short term hack (12-May-2020).  If we are running tests in
-# parallel then we need support in the contrib/dg-extract-results.*
-# scripts to merge the new result types generated by this file back
-# into the single unified summary file.  If this support is not in
-# place then the dg-extract-results script will exit with an error.
-#
-# The script changes need to first be merged into the gcc repository,
-# then copied over to the binutils-gdb repository.  The required
-# changes have been posted to the gcc list here:
-#
-# https://gcc.gnu.org/pipermail/gcc-patches/2020-May/545562.html
-#
-# But until these are merged into binutils-gdb the extra checks
-# offered by this file can only be done when the tests are not running
-# in parallel.
