The following flag combinations run into a CHECK in d8:
('--assert-types', '--stress-concurrent-inlining')
('--assert-types', '--stress-concurrent-inlining-attach-code')

All flags can be passed as clusterfuzz trials on d8 fuzzers and lead
to poor fuzzing outcomes. This lowers their probability as a
mitigation until a better solution is found.

Utf8Decoder used to use unibrow::Utf8::ValueOfIncremental, which had a

Quite embarassingly, the test that the WTF-8 decoder rejects surrogate
pairs was broken: the trailing surrogate was invalid.  (The range of the
second byte for leading surrogates is [A0,AF], and for trailing is
[B0,BF]).  Of course the actual functionality was broken, because the
code that detected surrogate pairs called IsSurrogatePair with swapped
arguments.

The optimization of a trap inside a branch is being removed. Since it
does not speed-up non-trapping programs, and it is quite narrow, it is
not worth the maintenance cost.

|exclude_imports| flag is set in some of the perfetto's proto_library
targets to indicate that we don't need to generate the proto-descriptor
for the protos included in those `x.proto` files. In this CL we use that
flag to conditionally pass `--include_imports` argument to protoc.

This is similar to the CL (https://crrev.com/c/2632759)
