We'd flatten upon compile anyway; and hashing the cons string also creates a local flattened version that's not cached. Change-Id: Ib5c82385ab009464b45bf1ceb289d04caaa77fcf Reviewed-on: https://chromium-review.googlesource.com/c/1309827Reviewed-by:

The slow path in Runtime_ArrayIndexOf allocates handles in each iteration over the input object. This CL gives each iteration its own handle scope in order to avoid consuming more and more memory the longer the loop runs. This can be observed e.g. by executing console.log(new Proxy(new Array(2**30), {}).indexOf(42)) which used to run out of memory on my machine.

Now that lazy deserialization has been removed, we can roll back all the mechanisms we introduced to support lazy single-builtin deserialization. This CL moves serialized builtin code objects (i.e. off-heap-trampolines in most cases) back into the startup snapshot. Support classes for builtin serialization and deserialization, as well as the builtins snapshot itself are removed. Templatization on the allocator class is removed as well.

CanCover is not transitive. The counter example are Nodes A,B,C such that CanCover(A, B) and CanCover(B,C) and B is pure. In this case the effect level of A and B might differ.

Port 15c31fe4 Original Commit Message: This introduces Word64 support for the CheckBounds operator, which now lowers to either CheckedUint32Bounds or CheckedUint64Bounds after the representation selection. The right hand side of CheckBounds can now be any positive safe integer on 64-bit architectures, whereas it remains Unsigned31 for 32-bit architectures. We only use the extended Word64 support when the right hand side is outside the Unsigned31 range, so for everything except DataViews this means that the performance should remain the same. The typing rule for the CheckBounds operator was updated to reflect this new behavior. The CheckBounds with a right hand side outside the Unsigned31 range will pass a new Signed64 feedback kind, which is handled with newly introduced CheckedFloat64ToInt64 and CheckedTaggedToInt64 operators in representation selection. The JSCallReducer lowering for DataView getType()/setType() methods was updated to not smi-check the [[ByteLength]] and [[ByteOffset]] anymore, but instead just use the raw uintptr_t values and operate on any value (for 64-bit architectures these fields can hold any positive safe integer, for 32-bit architectures it's limited to Unsigned31 range as before). This means that V8 can now handle huge DataViews fully, without falling off a performance cliff. This refactoring even gave us some performance improvements, on a simple micro-benchmark just exercising different DataView accesses we go from testDataViewGetUint8: 796 ms. testDataViewGetUint16: 997 ms. testDataViewGetInt32: 994 ms. testDataViewGetFloat64: 997 ms. to testDataViewGetUint8: 895 ms. testDataViewGetUint16: 889 ms. testDataViewGetInt32: 888 ms. testDataViewGetFloat64: 890 ms. meaning we lost around 10% on the single byte case, but gained 10% across the board for all the other element sizes.
