    slim up mem exprs to avoid line breaks in -fverbose-asm
    
    An asm operand with a "VIEW_CONVERT_EXPR<struct {
      [...]
    }>" will output the definition of the struct as asm code.  Oops.
    
    Enable TDF_SLIM in print_mem_expr to avoid such line breaks.
    
    
    for  gcc/ChangeLog
    
            * print-rtl.c (print_mem_expr): Enable TDF_SLIM in dump_flags.
