The easiest example is a long chain of BBs that don't otherwise use a

limiting the number of results doesn't help as no results are produced

Introduce a limit similar to the existing instructions-per-block limit.
This limit counts the total number of blocks checked. If the limit is

Fix handling of vaargs on PPC32 when going from regsave to overflow.
It can happen that when we only have 1 more register left in the regsave
area we need to store a value bigger than 1 register and therefore we
go to the overflow area. In this case we have to leave the last slot
in the regsave area unused and keep using overflow area. Do this
by storing a limit value to the used register counter in the overflow block.
Issue diagnosed by and solution tested by Mark Millard!

Remove all usages of "const" node pointer typedefs in the assoc containers.
The "const" pointer typedefs such as "__node_const_pointer" and
"__node_base_const_pointer" are identical to their non-const pointer types.
This patch changes all usages of "const" pointer type names to their respective
non-const typedef.
Since "fancy pointers to const" cannot be converted back to a non-const pointer
type according to the allocator requirements it is important that we never
actually use "const" pointers.
Furthermore since "__node_const_pointer" and "__node_pointer" already
name the same type, it's very confusing to use both names. Especially
when defining const/non-const overloads for member functions.

Cleanup node-type handling in the associative containers.
This patch is very similar to r260431.
This patch is the first in a series of patches that's meant to better
support map. map has a special "value_type" that
differs from pair<const Key, Value>. In order to meet the EmplaceConstructible
and CopyInsertable requirements we need to teach __tree about this
special value_type.
This patch creates a "__tree_node_types" traits class that contains
all of the typedefs needed by the associative containers and their iterators.
These typedefs include ones for each node type and node pointer type,
as well as special typedefs for "map"'s value type.
Although the associative containers already supported incomplete types, this
patch makes it official by adding tests.
This patch will be followed up shortly with various cleanups within __tree and
fixes for various map bugs and problems.
