Several forall_* macros have by now been eliminated from the code base as we
increasingly use C++11 ranged-for for those cases, or maybe don't need the
forall_* macro at all anymore. This commit just removes the unused ones from the
clang-format specification, no actual code changes.
In current version of clang-format, this leaves groupings alone and just
sorts within the group.
For example, given a list of includes like:
```
include "boolbv.h"
include <util/std_types.h>
include <util/std_expr.h>
include <util/arith_tools.h>
include <util/base_type.h>
include <util/pointer_offset_size.h>
include <util/c_types.h>
```
These will be sorted to:
```
include "boolbv.h"
include <util/arith_tools.h>
include <util/base_type.h>
include <util/pointer_offset_size.h>
include <util/std_expr.h>
include <util/std_types.h>
include <util/c_types.h>
```
Note the "groups" are left untouched, the ordering occurs within the
groups
