This patch normalizes the casing of hexadecimal digits in escape
sequences of the form `\xNN` and integer literals of the form
`0xNNNN`.
Previously, the V8 code base used an inconsistent mixture of uppercase
and lowercase.
Google’s C++ style guide uses uppercase in its examples:
https://google.github.io/styleguide/cppguide.html#Non-ASCII_Characters
Moreover, uppercase letters more clearly stand out from the lowercase
`x` (or `u`) characters at the start, as well as lowercase letters
elsewhere in strings.

construction. This change adds a CHECK to enforce this property.
Additionally, this change exposed several cases where we were not generating

* 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.

currently, which means lots of noise in bug reports and increased
workload for the clusterfuzz sheriffs.
After this change, all bugs of the same category ("compiles !=

This requires us to fix them soon after reporting, as they will hide

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.

If the fuzzer input cannot be executed in the interpreter within a step
limit, then the interpreter does not calculate the result but instead
finishes with a RangeError. The problem with the input of the bug report
was that the interpreter finished with that RangeError, but the
execution of the compiled code still returned a result, which was
naturally not a RangeError and therefore caused the result check to fail.
With this CL the compiled code is not even executed when there is a
RangeError after the execution in the interpreter. Thereby we also
avoid executing an infinite loop.

After landing both CLs, we can later also get rid of
InstantiateModuleForTesting.

This CL removes unnecessary code duplication in the fuzzer code. Instead
of having special testing functions to compile and instantiate a
WebAssembly module, we now just call SyncCompile and SyncInstantiate.
This also fixed a problem when the fuzzer generated a GrowMemory
instruction.

The wasm-code fuzzer used different parameters for the interpreter and
the generated code due to a typo. This typo is fixed by this CL.

In a recent CL I moved the corpus of the wasm fuzzer and of the
wasm-asmjs fuzzer to a different directory
(wasm_corpus and wasm_asmjs_corpus) so that the corpus is not executed
on the try-bots. With this CL I remove the old corpus from the
.gitignore file.
In addition I removed the hooks for wasm_corpus and
wasm_asmjs_corpus from the V8 DEPS file, because in a V8 checkout
they are not used anyway.
I also added code to the test runner to delete all *.wasm files
from the directories test/fuzzer/wasm and test/fuzzer/wasm_asmjs.
This code should be removed in a week, but it will help my coworkers
to cleanup their V8 checkout.
