The "DumpAsyncTaskStacksStateForTest" method just prints three counts,
which is not helpful for the fuzzer and can create unwanted output
during fuzzing.

LoadImmutable represents a load from a position in memory that is known
to be immutable, e.g. an immutable IsolateRoot or an immutable field of
a WasmInstanceObject. Because the returned value cannot change through
the execution of a function, LoadImmutable is a pure operator and does
not have effect or control edges.
This will allow more aggressive optimizations of loads of fields of
the Isolate and Instance that are known to be immutable.
Requires that the memory in question has been initialized at function
start even through inlining.

Note: We may reconsider this approach once we have escape analysis for
wasm, and replace it with immutable load/initialize operators that live
inside the effect chain and are less restriced.

Stepping code that is left on the stack will repeatedly call the
WasmDebugBreak function. This has no observable effect, except for
severe slowdown of execution. In the linked bug, we were executing at
least another few million instructions in the same frame, so it appeared
that it never finishes.

This CL fixes that by replacing stepping code with non-stepping code if
the WasmDebugBreak runtime function is called from stepping code but we
are not stepping (any more).
Adding a test for this is difficult, since this only has an effect on
performance.

Especially "kNoReturnCall" is confusing, because it can be read as "a
call that does not return", which is not meant here.
This CL renames the enum to "TailCall" with the boolean values
"kTailCall" and "kNoTailCall". Uses of the enum can be simplified to
boolean checks directly.

The frame types to skip are only used in the constructor, hence pass
them as an initializer_list instead of template arguments.

This fixes a bug in which CompileTopLevel has a pending exception
that is never taken care of. This CL adds a check for the output
of CompileTopLevel and clears the pending exceptions if existent.

Generic wasm wrappers are enabled by default now (since
https://crrev.com/c/2562241), so we can remove the flag from the
nooptimization variant. Instead, we should have a configuration which
tests --no-wasm-generic-wrapper to find bugs in the compiled wrappers
earlier.

Also add an entry for contradictory flags, and reformat that list to
respect the 80 columns limit.

If liveedit patches a script there might be a mismatch between
the bytecode on a stackframe and the bytecode on the JSFunction
for that same frame. This allows the patched bytecode on the
JSFunction to be flushed which breaks the invariant that all
JSFunctions with live stack activations are compiled. To prevent
this disable bytecode flushing when liveedit patches a script.

This is a more canonical type name, and is in line with {kVoidCode}.
