9733dacc5c [test] Refactor testrunner (3)
- removed some 'feature envy' instances:
  - created a AugmentedOptions class to take care of non trivial option look-ups
  - moved some calculation closer the the actual data
- promoted parameter that was passed around a lot (options) to filed in the offending class
- similar object creation looks a bit more similar
- CommandContext provides a wrapper that ensures resource de-allocation
- separate tests from standard and num_fuzz runners
- added a couple of more tests to improve coverage

This is still in flux. But further changes risk creating a disconnect between the original implementation and further refactorings.

0f4a62c04c [isolate] Strengthen check for builtins results
The CHECK was checking that we return the exception sentinel if an
exception is pending. The other way is actually equally important: If we
return the exception sentinel, a pending exception must be scheduled.

Since the CEntry stub assumes that all values returned from runtime
functions are valid tagged values (pointing into the JS heap), do also
check that. This check would have prevented the linked issue.

7e0294dcfa [wasm][api] Introduce API to let the embedder resolve wasm promises
Asynchronous WebAssembly compilation returns the compilation result
through resolving a result promise. So far the result promise was
resolved through V8-internal APIs. This caused problems, because
resolving promises requires correct handling of microtasks, and
microtasks are controlled by the embedder, and not by V8.

This CL adds an API to allow the embedder to resolve the result
promise itself, and handle microtasks as necessary.

The use of the new API is available in a full CL, without API dance:

the background thread, instead of scheduling incremental tasks on the
main thread. This allows us to remove almost all special
handling for code pages in the sweeper and allows us to off-load more
work from the main thread.

efb80afe2a [wasm] Add flag to disable the wasm native module cache
The native module cache makes it difficult to test deserialization,
because the native module just gets loaded from the cache instead of
deserializing the serialized module. This CL adds a new flag,
--wasm-native-module-cache-enabled, to control whether the native module
cache is enabled or not. The cache gets disabled by handling all modules
like asm.js modules when the cache gets disabled, as the cache is not
used for asm.js.

The name of the flag is positive (i.e.
`enabled` instead of `disabled`) to avoid double negation. The flag is
true by default, and set to false in tests.

cc692a98de [maglev] Fix phi injection for empty blocks
Empty blocks were skipped when performing register merges (since they
don't have a state), but we were still doing phi value injection only
when visiting the empty block. This meant that empty blocks have
inconsistent register state with the nodes they are trying to use.

Fix this by removing the skipping code, and adding a register merge
state to empty blocks.

b22fcf9f79 Revert "[regalloc] add hint for operands in gap moves."
This reverts commit c14b3e4d11.

Reason for revert: https://crbug.com/1335195

Original change's description:
> [regalloc] add hint for operands in gap moves.
>
> To eliminate unnecessary move instructions from register to fixed register. We check the fixed register hint for operands in move gaps
> when building LiveRanges. If a to_operand has a hint_operand (with fixed register), then set the hint_operand for from_operand too. This can avoid the register allocator ignore hint information about fixed register.

function, most of which will be throw away.

Add a bit to SharedFunctionInfo to note whether concurrent compilation

c2ede7acd2 [maglev] Fix dead bytecode visit (again)
A few more fixes for visiting bytecodes that are known to be dead:

  * Change JumpLoop dead frame merging to remove the loop predecessor,
    by moving the loop predecessor to be the last in the list and
    allowing it to be dropped the same way as other predecessors.
  * Remove the bytecode walk in EmitUnconditionalDeopt, opting instead
    to check for null current_block in the real bytecode visitor. This
    allows us to handle the case where the start of a basic block is
    dead, but there's no fallthrough into it, so it wouldn't be visited
    by the loop in EmitUnconditionalDeopt.

6f9df3e74e cppgc: young-gen: Support young generation with pointer compression
Currently, young generation assumes that all the on-heap pointers are
compressed, which is currently not the case due to the backing-store
pointers in Blink. Fixing collections to have Member<> is not easy,
because the inlined collections may have the semantics that
 backing_pointer_ == inlined_buffer_;
where the inlined_buffer_ can be off-heap (e.g. on stack).

The CL introduces another type of barrier specifically for uncompressed
pointers. The followup is to use that barrier from Blink.
