Update config=sanitize and fuzz targets

Browse Source 
We used to need to silence float-divide-by-zero and float-cast-overflow
sanitizers since clang used a finite valid floating point value range.
Fortunately, since clang-9 UBSAN properly handles various primitive
operations per IEEE-754 so we no longer need this workaround.

Also use fork=16 mode for fuzz targets to make it easier to run fuzzing
locally.
