Alexandre Oliva 586e32583a compare_tests: distinguish c-c++-common results by tool
When compare_tests compares both C and C++ tests in c-c++-common, they
get the same identifier, so expected differences in results across
languages become undesirably noisy.

This patch adds tool identifiers to tests, so that runs by different
tools are not confused by the compare logic.

It also fixes a bug in reporting differences, that would attempt to
print an undefined fname (the definitions are in subshell loops), and
adjusts the target insertion to match tabs in addition to blanks after
colons.


for  contrib/ChangeLog

	* compare_tests: Add tool to test lines.  Match tabs besides
	blanks to insert tool and target.  Don't print undefined fname.

Usage: $0 [-strict] PREVIOUS CURRENT
Compare the PREVIOUS and CURRENT test case .sum files, reporting anything of interest.
If PREVIOUS and CURRENT are directories, find and compare any *.sum files.
Unless -strict is given, these discrepancies are not counted as errors:
missing/extra .sum files when comparing directories
tests that failed in PREVIOUS but pass in CURRENT
tests that were not in PREVIOUS but appear in CURRENT
tests in PREVIOUS that are missing in CURRENT
Exit with the following values:
0 if there is nothing of interest
1 if there are errors when comparing single test case files
N for the number of errors found when comparing directories
