[libfuzzer] Disable failing DFSan-related tests
These have been broken by https://reviews.llvm.org/D104494.
However, `lib/fuzzer/dataflow/` is unused (?) so addressing this is not a priority.

[libfuzzer] Disable failing DFSan-related tests
These have been broken by https://reviews.llvm.org/D104494.
However, `lib/fuzzer/dataflow/` is unused (?) so addressing this is not a priority.
Added TODOs to re-enable them in the future.

[dfsan] Add full fast8 support
Complete support for fast8:
- amend shadow size and mapping in runtime
- remove fast16 mode and -dfsan-fast-16-labels flag
- remove legacy mode and make fast8 mode the default
- remove dfsan-fast-8-labels flag
- remove functions in dfsan interface only applicable to legacy
- remove legacy-related instrumentation code and tests
- update documentation.

[DFSan] Add efficient fast16labels instrumentation mode.
Adds the -fast-16-labels flag, which enables efficient instrumentation
for DFSan when the user needs <=16 labels. The instrumentation
eliminates most branches and most calls to __dfsan_union or
__dfsan_union_load.
