Original Commit Message:
As of https://crrev.com/c/2629465, Simd tests cannot pass on
architectures without Simd support. Tests will need to be
re-enabled once Simd support is fully implemented on PPC.

This CL introduces a test runner flag to detect if webassembly has been
disabled. Since all tests that require wasm are alrady skipped in
lite mode, we introduce a has_webassembly flag for the test runner which
checks for v8_enable_webassembly=true and v8_enable_lite_mode=false.
As a drive-by, we also do not set the V8_ENABLE_WEBASSEMBLY
preprocessor flag if lite mode is enabled.
The status files are updated by splitting wasm tests from the
"lite_mode" section and checking for "not has_webassembly" instead.
Note that the v8_enable_webassembly=false configuration is not tested
on any bot currently, but I will make sure that all tests keep passing
on further changes in this configuration.

The serializer currently cannot handle a heap state containing
arbitrary compiled Code objects. As a quick fix for the
--stress-snapshot d8 flag, we clear compiled data from the isolate
prior to the serialize-deserialize-verify pass.
With this change, mjsunit tests pass on x64.
The %SerializeDeserializeNow() runtime function would require more
work, since it is not possible to mutate the heap to this extent while
still preserving a runnable host context and isolate. We will need
another solution there.
Drive-by: Skip the stress_snapshot variant except for the mjsunit
suite.

Add a case for kWasmS128 in Spill. We encounter this in the
wasm-trace-memory-liftoff test, but that test was skipped on ARM and
ARM64 due to insufficient implementation of Liftoff on those archs. But
with recent changes, they are now capable of running this particular
test, so we enable it.
Drive-by fix for incorrect size used in vld1 for filling S128 values.

For memory tracing, output a 'T' for Turbofan code and an 'L' for
Liftoff code. To do this, the WasmCodeWrapper now has some dispatch
functions which work for both on-the-heap and off-the-heap code.
We can probably refactor more code by having this mechanism.
Since the output of --wasm-trace-memory differs now between Turbofan
and Liftoff, the message test is split in two.

This adds a --stress-validate-asm flag intended to stress test the
validator by running against every single function, independent of
whether a "use asm" directive is present. It mainly tests negative
cases because barely any function in our test corpus will be a valid
