First version of an assembly language decoder.
...
It is slower than the C decoder for now because it
falls off the fast path too often. But it can
successfully decode varints, fixed32 and fixed64.

Split inttable into a hash part and an array part.
...
upb_inttable() now supports a "compact" operation that will
decide on an array size and put all entries with small enough
keys into the array part for faster lookup.
Also exposed the upb_itof_ent structure and put a few useful
values there, so they are one fewer pointer chase away.

Remove upb_dstate and specialize upb_decode_fixed for perf improvement.
...
The compiler wasn't keeping upb_dstate in memory
anyway (which was the original goal). This
simplifies the decoder. upb_decode_fixed
was intended to minimize the number of branches,
but since it was calling out to memcpy as a
function, this turned out to be a pessimization.

Unfortunately this degrades hash table lookup performance by
about 8%, which affects the streaming benchmark for googlemessage1
by about 5%. We could get this back at the cost of some memory,
but it would be nice to avoid that.
