Make proto2 benchmarks use ParsePartial, to make results vs upb more comparable.
...
ParsePartial does not check that required fields are set, which upb
also currently does not do.
This sped up proto2 reflection by 40%, but upb is still 7x faster in
a comparable test (instead of 11x, like before).

Change the API for getting the bootstrapped defs.
...
The symtab that contains them is now hidden, and
you can look them up by name but there is no access
to the symtab itself, so there is no risk of
mutating it (by extending it, adding other defs
to it, etc).

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.
