Fuzzilli is open source fuzzer by Samuel Groß (saelo@google.com)
that can be used to find bugs in v8 javascript engine. As we want
to automate fuzzing for current versions of v8, we want to merge
fuzzilli toolkit into v8 code, so that fuzzer can automatically
update to the newest version.
So far Fuzzilli has been maintained at

https://crrev.com/c/2072858 rewrote the implementation of non-unicode
ignore-case matches to comply with the JS spec in some corner
cases. It fixed character matches and character class matches.
We missed a similar bug in the implementation of back references. This
CL fixes that bug.
The main change is in regexp-macro-assembler.cc, where
CaseInsensitiveCompareUC16 is split into CaseInsensitiveCompareUnicode
(which has the same semantics as before) and
CaseInsensitiveCompareNonUnicode (which has the semantics described
here: https://tc39.es/ecma262/#sec-runtime-semantics-canonicalize-ch).
Most of the rest of the patch undoes https://crrev.com/c/2081816 to
once again make the unicode flag available to the macroassembler, so
that we can decide which helper function to call.
The testcase is a version of test/intl/regress-10248.js, modified to
test backreferences.

This CL makes the test stricter by requiring specific string shapes;
before it was possible to skip verification if strings were
short-circuited, which I believe is no longer possible due to thin
strings.
I also added a regression test for the linked bug, which requires
a String.p.split call on a two-byte-in-one-byte string with an empty
string separator argument.

In production, we will always pass a pointer to the decoded module. The
only reason for the existance of the nullptr checks is that tests
sometimes don't pass a module here. Hence we pay in production code for
a test-only feature.
This CL fixes this by always passing a module pointer from the decoder
tests. This even simplifies the code a lot by removing redundant code.
The {TestModuleBuilder} class was moved before the definitions of the
{FunctionBodyDecoderTest} class in order to be able to reuse it there.
It's unmodified otherwise.

The SourcePositionTableBuilder unconditionally allocates heap memory for
every Liftoff compilation. This shows up with 1-2% of compilation time
in profiles. Hence move the vector contained in the
SourcePositionTableBuilder into the compilation zone. Such a zone
already exists for both Liftoff and TurboFan, so we can easily save
allocations this way.

This change adds more granular control to the behavior that was
previously controlled by the single flag --turbo-profiling. With this
change, it becomes possible to:
- output information only about builtins, ignoring functions compiled at
runtime
- skip the very slow process of writing the schedule and disassembly for
all builtins, if you only want the block counts and don't need verbose
output
This change also moves the output step from Shell::OnExit to
Isolate::DumpAndResetStats so that it's more consistent with other
features and works in hosts other than d8.

This adds support for multiple isolates sharing the same module but
setting different breakpoints. This is simulated by having a debugger
test that runs in the "--isolates" variant, i.e. two isolates running
the same test at the same time. Both isolates will set and remove
breakpoints.
The DebugInfo will keep a separate list of breakpoints per isolate, and
when recompiling a function for debugging it will respect all
breakpoints in all isolates.
In order to ensure consistency if multiple isolates are setting or
removing breakpoints simultaneously, we go back to a more coarse-grained
locking scheme, where the DebugInfo lock is held while re-compiling
Liftoff functions.
While recompilation will install the code in the module-global code
table and jump table (and hence all isolates will use it for future
calls), only the stack of the requesting isolate is rewritten to
immediately use new code. This is OK, because other isolates are not
interested in the new breakpoint(s) anyway.
On {SetBreakpoint}, we always need to rewrite the stack of the
requesting isolate though, even if the breakpoint was set before by
another isolate.
Drive-by: Some fixes in SharedFunctionInfo in order to support setting
breakpoints via the Debug mirror.
