Doug Moore 6f251ef228 radix_trie: simplify ge, le lookups 
Replace the implementations of lookup_le and lookup_ge with ones
that do not use a stack or climb back up the tree, and instead
exploit the popmap field to quickly identify the place to resume
searching if the straightforward indexed search fails.

The code size of the original functions shrinks by a combined 160
bytes on amd64, and the cumulative cycle count per invocation of
the two functions together is reduced 20% in a buildworld test.
