To reduce the amount of arithmetic performed in the various radix tree
functions, reverse the numbering scheme for the levels.  The highest
numbered level in the tree now appears near the root instead of the leaves.

sh: Remove linked list of stack marks.

The linked list of stack marks may cause problems if the allocation stack is
used between an exception and a higher-level popstackmark(), as it may then
touch a stack mark that is local to a function which has returned.

Also, the adjustment compares to a pointer passed to realloc(), which is
undefined behaviour.

Instead of adjusting stack marks when reallocating stack blocks, ensure that
such an adjustment is never necessary by fixing a small piece of memory in
place at a stack mark. This also simplifies the code.

To avoid the problems reported in bin/175922, it remains necessary to call
setstackmark() after popstackmark() if the stack mark remains in use.

Don't use the old stack-walking code with
EABI ARM kernels or clang-compiled ARM kernels.

This fixes a crash seen in clang-compiled ARM
kernels that include WITNESS.

This code could be easily modified to walk the stack
for current clang-generated code (including EABI)
but Andrew Turner has raised concerns that the
stack frame currently emitted by clang isn't actually
required by EABI so such a change might cause problems
down the road.

In case anyone wants to experiment, the change
to support current clang-compiled kernels
involves simply setting FR_RFP=0 and FR_SCP=1.
