Eliminated bounds checks inside parsing a field.
Each field parser gets 16 bytes of slop. This requires using a patch
buffer at end-of-buffer.
This addes 80% of what is needed to support a pull parser with a data
callback, since the main parser is now tolerant to buffer flips.
There is a ~4% performance regression and 12% code size regression in
upb/decode.c:
name old time/op new time/op delta
ArenaOneAlloc 21.0ns ± 0% 21.6ns ± 0% +2.87% (p=0.000 n=12+12)
