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.

symtab: use longjmp() for errors and avoid intermediate table.
...
We used to use a separate "add table" during the upb_symtab_addfile()
operation to make it easier to back out the file if it contained
errors. But this created unnecessary work of re-adding the same symbols
to the main symtab once everything was validated.
Instead we directly add symbols to the main symbols table. If there is
an error in validation, we remove precisely the set of symbols that
were already added.
This also requires using a separate arena for each file. We can fuse
it with the symtab's main arena if the operation is successful.

Drop C89/C90 support and MSVC prior to Visual Studio 2015.

upb previously attempted to support C89 and pre-2015 versions
of Visual Studio. This was to support older compilers with
limited C99 support (particularly MSVC). But as of last August,
even gRPC has dropped support for MSVC prior to 2015

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:
