0cdf348c5c [wasm] Remove some WASM conversion magic constants
This CL removes some magic numbers used to convert floating values into
integer values, and the corresponding comments describing how they were
computed. It replaces these tests with template function is_inbounds()
that makes the compiler automatically generate the appropriate constants
and tests.

Note: This CL only changes the WASM interpreter to use is_inbounds(). Tests
have not yet been updated to guarantee that this change did not break anything.

Note: This change was initialed by a comment by @clemensh in
CL https://chromium-review.googlesource.com/c/v8/v8/+/834670.

a97298bae5 Use --untrusted-code-mitigations flag also for JS
Remove the --extra-masking and --mask-array-index flags. Instead, use
--untrusted-code-mitigations directly.
This also changes the default for these flags: There were off by
default so far, but --untrusted_code_mitigations is on by default.

Store the value of the untrusted_code_mitigations flag in the
CompilationInfo in order to ensure that it stays consistent during the
compilation of one function.

2b4cc835f1 [builtins] Port EnqueueMicrotask to CSA.
Previously the Promise builtins would always use a runtime function to
schedule a new microtask, which is unnecessarily expensive. Since the
runtime function only adds the microtask to a FixedArray (potentially
growing that array) and increments the number of pending microtasks, it
is fairly straight-forward to do this in CSA land instead.

This change improves the Bluebird benchmarks by 2-4% on average.

9f7d440e98 [test] Check output on the worker process.
I added additional exception logging in the execution.py since
errors in processing results were really difficult to debug.

There is a problem on Windows with class serialization when
it comes from dynamically loaded module. To fix it I moved all
output processors to the tools/testrunner/outproc/ and import
them in test/*/testcfg.py.

6328c56570 Reland "[turbofan] add value input to DeadValue"
DeadValue was a constant node of type None. This is unsound in the
presence of re-scheduling. This CL adds a value input to DeadValue,
which preserves the dependency on the original node of type None.

This reland addresses the bug that the EffectControlLinearizer could destroy dependencies of DeadValue by attaching DeadValue nodes to the effect chain in the EffectControlLinearizer.

6b050c0324 [builtins] Use appropriate ConvertReceiverMode in Promise builtins.
The Promise builtins call out to arbitrary JavaScript a lot, but always
use the generic Call builtin with the "any" mode, which means that the
builtin has to dispatch based on the type of receiver. Yet these
builtins always know for sure that the receiver is either undefined or
definitely not null or undefined. So this changes the builtins to pass
the correct ConvertReceiverMode and thus save a couple of checks.

4b107b9ec9 [wasm][fuzzer] Add locals
This adds support for get_local and set_local to the wasm compile
fuzzer. Each function will have between 0 and 32 locals of random type.
For set_local, we generate a value of the respective type and store it
in the local. For get_local, we load any local and convert it to the
wanted type.
Note that with get_local, we now also check that parameters are passed
correctly between functions.

Drive-by: Fix parameters passed to the main function (was [1,2,3] for
the interpreter, but [1,1,1] for compiled code).

71605b3ea4 [test] Move has unexpected output to outproc.
Expected outcomes optimized to serialize [PASS] as None.

Keeping expected outcomes inside output processors should be
optimized in the future. Few possible optimizations:
- separate classes for tests that are expected to PASS - done as
an example in mozilla test suite.
- cache output processors inside testcase.
- share output processors between copies of the same test - needs
some updates to the create_variant to update outproc only if
expected outcomes changed.
