    gdb/testsuite: remove get_compiler_info calls from gdb.exp and dwarf.exp
    
    We don't need to call get_compiler_info before calling
    test_compiler_info; test_compiler_info includes a call to
    get_compiler_info.
    
    This commit cleans up lib/gdb.exp and lib/dwarf.exp a little by
    removing some unneeded calls to get_compiler_info.  We could do the
    same cleanup throughout the testsuite, but I'm leaving that for
    another day.
    
    There should be no change in the test results after this commit.
