Fixed a critical bug on 32-bit builds, and added much more Kokoro testing.
...
There was a bug in our arena code where we assumed that
sizeof(upb_array) would be a multiple of 8. On i386 it was
not, and this was causing memory corruption on 32-bit builds.

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:
