Subject: [PATCH 0/2] fib semantic matching

fib_semantic_match() creates unnecessary overhead on route lookups
for two reasons:

1) It does type validation at run time instead of when we insert
   the route.

2) Argument passing is expensive because it does it's work as
   a seperate function.

So these two patches move type validation into fib_create_info(),
and then we inline fib_semantic_match() completely into check_leaf().

This is good for 50+ cycle gain on output route lookups on Niagara2.
