2270c0eaaa [wasm][fuzzer] Run micro tasks after each fuzzer execution
This asserts that we run e.g. GC finalization tasks. Without that, we
might run ouf of memory.

3df442d738 [wasm] Keep NativeModule alive in BackgroundCompileScope
We need to ensure that the NativeModule stays alive while any
{BackgroundCompileScope} exists, because during that time we hold
shared ownership of the mutex in the {BackgroundCompileToken}. If the
{NativeModule} dies during that period, we would need to get exclusive
ownership of the mutex and deadlock.

This change requires holding a {std::weak_ptr<NativeModule>} in the
BackgroundCompileToken instead of a raw pointer, hence it can only be
initialized after the NativeModule was created. This is done via a
separate {InitCompilationState} method.

82fdb91505 [regexp-builtins-fuzzer] Print generated source in verbose mode
My standard procedure for debugging regexp builtin fuzzer finds is to
turn on verbose mode and run the repro. This extends verbose output to
include the generated script which contains e.g. the regexp pattern,
the subject string, and the actual function call.

Every testsuite configuration consist of at least 30% code duplication.

The code age ranges from 10 years old to 5 years old. Implementing anything that
touches the testsuite code becomes a technical fight to the death.

This CL removes all the duplication by refactoring the common functionality.

This CL contains structural changes without any logical changes % small bug

a1ff298d4f [wasm] Move Isolate management to WasmEngine
The WasmCodeManager held a list of all Isolates that use the
WasmEngine/WasmCodeManager (those two are 1:1).
Since we want to move all isolate-specific tasks (like code logging and
compilation callbacks) to the WasmEngine, this CL moves this management
from the WasmCodeManager to the WasmEngine. We now have a bidirectional
mapping from NativeModules to the Isolates that use them, and from an
Isolate to all the NativeModules it uses (n:n).
The IsolateData struct will be extended in follow-up CLs to hold things
like the ForegroundTaskRunner. The Isolate* in the NativeModule /
CompilationState will eventually be removed.

                                  -> --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.

For short inputs (<= size of the type we want to generate), we fell back
to just generating constants. This CL changes that to only fall back to
constants once a single byte remains, and adds options to use constants
already before that.

cc70a6b050 [wasm] Rename GrowMemory to MemoryGrow
The "grow_memory" opcode was renamed to "memory.grow", and the spec
repo was updated to use kExprMemoryGrow internally instead of
kExprGrowMemory (https://github.com/WebAssembly/spec/pull/720).
This CL does the same change for v8.

Drive-by: Rename "current_size" to "memory.size", and a minor cleanup
in wasm-graph-builder.js to bring it in line with the version in the
js-api tests in the spec repo.

3e545e4045 Reland "[wasm] Implement the new API for WebAssembly.instantiateStreaming"
The problem was that in AsyncCompileJob::FinishModule we allocate a
handle, but when this function is called from streaming compilation, then
there was no HandleScope around AsyncCompileJob::FinishModule. This issue
was fixed in another CL, https://crrev.com/c/1172357. This CL is just a
rebase of the original CL.
