    gdb/testsuite: use test_compiler_info in gcc_major_version
    
    The procedure gcc_major_version was earlier using the global variable
    compiler_info to retrieve gcc's major version.  This is discouraged and
    (as can be read in a comment in compiler.c) compiler_info should be
    local to get_compiler_info and test_compiler_info.
    
    The preferred way of getting the compiler string is via calling
    test_compiler_info without arguments.  Gcc_major_version was changed to
    do that.
