8e11cc395a Enable cpplint 'runtime/references' warning
Cpplint usually checks for non-const reference arguments. They are
forbidden in the style guide, and v8 does not explicitly make an
exception here.
This CL re-enables that warning, and fixes all current violations by
adding an explicit "NOLINT(runtime/references)" comment. In follow-up
CLs, we should aim to remove as many of them as possible.

b9854da1ec [fuzzer] Remove the wasm section fuzzers
The fuzzers were already removed on the chrome side and therefore
inactive, see https://crrev.com/c/1194228.

dad67377c3 [wasm] "Vectorize" fuzzer
Instead of passing {uint8_t*, size_t} pairs as arguments, pass
{Vector<uint8_t>}. This is less error prone and {Vector} provides some
helpful methods.

77e4b2de2d [wasm] wasm-fuzzer: Add ability to generate test case
Other fuzzers already have this ability. This CL adds it to the fuzzer.
The input has to be valid bytes, otherwise we cannot generate the text
representation.

ea08828bb3 [wasm fuzzer] Require AST fuzzer modules to validate
The Wasm AST-based fuzzer is supposed to create valid modules by
construction. This change adds a CHECK to enforce this property.

Additionally, this change exposed several cases where we were not generating
valid modules before:
  * Block types did not match up correctly
  * Memory operations could have invalid alignments
  * Storing an i64 could generate an i32 argument incorrectly.
This CL includes fixes for these issues as well.

0afe2524c0 [wasm] Add fuzzing for Liftoff
Each valid memory module generated by one of the wasm fuzzers will now
also be executed in Liftoff, and the result of the execution will be
compared against the interpreted result.

7b53a0e010 [wasm] Avoid executing infinite loops in the wasm fuzzers
The wasm-async fuzzer uses the bytes provided by the fuzzer engine
directly as wasm module bytes, compiles them with async compilation, and
then tries to execute the "main" function of the module. This "main"
can have an infinite loop which causes a timeout in the fuzzer. With
this CL the "main" function is first executed with the interpreter. If
the execution in the interpreter finishes within 16k steps, which means
that there is no infinite loop, also the compiled code is executed.

I added the raw fuzzer input as a test case because in this case I
really want to test the fuzzer and not V8.

eb64b26f8f [cleanup][wasm][fuzzer] Share code among the different fuzzers.
With this CL we share code among the wasm fuzzers which construct a
module and run it in the interpreter and as compiled code.The fuzzers
themselves only contain the code now which creates the module and the
parameters.
