    [testsuite] Fix retrieval of testname
    
    When gcc-dg-runtest is used to run a test the test is run several times
    with different options. For clarity of the log, the test infrastructure
    then append the options to the testname. This means that all the code
    that must deal with the testcase itself (eg. removing the output files
    after the test has run) needs to remove the option name.
    
    There is already a pattern (see below) for this in several place of the
    testsuite framework but it is also missing in many places. This patch
    fixes all of these places. The pattern is as follows:
    
    set testcase [testname-for-summary]
    ; The name might include a list of options; extract the file name.
    set testcase [lindex $testcase 0]
