    c++: improve template/crash90.C
    
    In r208350 I improved the diagnostic location of the initializer-list
    pedwarn in C++98 mode on crash90.C, but didn't adjust the testcase to verify
    the location, so reverting that change didn't break regression testing.
    
    gcc/testsuite/ChangeLog:
    
            * g++.dg/template/crash90.C: Check location of pedwarn.
