Fixup testcases outputting own name as a test name and standardize failed compilation messages Changes in v3: - Adjusted some testcases where the message "failed to compile" was not unique. Changes in v2: - Addressed comments from reviewers. - Fixed spurious whitespaces. - Changed compilation failure messages that included source/binary paths to ones that are short and deterministic. --- Another bit of cleanup to the testsuite. We have a number of tests that are not honoring the rule of not outputting their own name as a test name. I fixed up all the offenders i could find with the following regular expression: "(xfail|kfail|kpass|fail|pass|unsupported|untested) ([A-Za-z0-9]+|\\\$(.)*testfile(.)*)\.exp$" gdb/testsuite/ChangeLog:
