Liftoff is not fully feature complete yet. To test that Liftoff can
bailout to TurboFan also for debugging, this CL adds
* an opcode that is only implemented in TurboFan
* a flag that allows that opcode to be compiled with TurboFan
* a bailout for this opcode to Liftoff.

To properly test tier-up in the V8 test suite, change the test variant
previously called --turbo-nci-as-highest-tier to
--turbo-nci-as-midtier. As a midtier (between ignition and turbofan),
all major parts of the NCI pipeline (codegen, caching inside the same
native context, tier-up) are exercised by test suite.

Just like the optimized code cache, the compiler should check the
isolate cache for NCI code objects and return them if they exist.
Drive-by: Skip additional tests to fix the nci_as_highest_tier test
variant. These are related to interactions with deoptimization, which
NCI code doesn't fully support yet.

With work on NCI proceeding, it makes sense to test multiple
pipeline configurations.
The nci variant (passes --turbo-nci) now spawns dedicated NCI
compilation jobs and inserts generated code into the code cache.
The nci_as_highest_tier variant (passes --turbo-nci-as-highest-tier)
simply replaces TF with NCI code (no extra jobs, no extra caching).
This mode stresses NCI generated code more than the nci variant, in
which NCI code only runs on cache hits.

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.

This piggy-backs off similar support for lite mode, which silently skips
tests that require optimization in lite (and now jitless) modes.

--jitless -> --no-opt
-> --no-validate-asm
-> --wasm-interpret-all -> --no-asm-wasm-lazy-compilation
-> --no-wasm-lazy-compilation
Note that wasm still isn't supported in jitless mode since it generates
code at runtime even with --wasm-interpret-all.
Drive-by: Fail early when trying to compile irregexp code in jitless
mode.

This CL disables RX (read and execute) permissions for Code memory
when in jitless mode. All memory that was previously allocated RX
is now read-only.

The SFI's flags can be changed by the mutator while the concurrent marker is checking
the flags for bytecode flushing. None of the flag bits checked for bytecode flushing
are changed, however since they are in an int32 field TSAN will complain if any of the
other flags are changed while reading from another flag. Fix this by making the flags
use the RELAXED_INT32_ACCESSORS.
