GraphAssembler creates Phi nodes and creates additional inputs to them depending on how many jumps go there. If the typer decorator is active, it will type the Phi node at creation time. GraphAssembler was not aware of types (until recently it was not used while the graph is typed) and did not update the Phi type with each new input. This CL fixes that.

Load extends always load 64-bits. Previously, we were setting the max alignment to be the size_log_2 of the load_type.

Avoid the SFI lookup in the script's weak SFI list, which could fail if the function was somehow GCed between allocation and finalization, and instead hold a Handle to each finalizing SFI in the finalization data structure. For similar reasons, also check that the compiled function to have its compilation finalized is still compiled by that point, because it could have been bytecode flushed.

The existing non-builtin implementation is returning wrong results. For example, given the value 63 as a uint8_t it returns 38 (should be 6). The new implementation follows the naive algorithm presented in figure 5-1 in Hacker's Delight section 5-1. Note that the algorithm in the book is designed for 32 bit numbers, so we extended it to support 64 bit as well.

When reducing api calls, TurboFan infers the maps of the receiver and tries to drop the compatibile receiver checks if we can verify that it is safe to do so. One of these checks involves checking that the holder is same across all of the receiver maps. However, when receiver itself is the holder the existing checks prevent TurboFan from optimizing the api calls.

Add a new OffThreadObjectDeserializer, which can deserialize a snapshot into an OffThreadIsolate. This involves templating the Deserializer base class on Isolate, and amending OffThreadHeap to be able to create Reservations same as the main-thread Heap can. Various off-thread incompatible methods are stubbed out as UNREACHABLE in OffThreadIsolate overloads. There is currently no API entry into the off-thread deserialization, but under --stress-background-compile it now runs the CodeDeserializer (i.e. code cache deserialization) in a background thread.

This CL implements stack scanning for cppgc. Given a value on the stack, the MarkingVisitor uses PageBackend::Lookup to checks whether that address is on the heap. If it is, BasePage::TryObjectHeaderFromInnerAddress (introduced in this CL) is used to get the relevant object header. Note that random addresses on the heap might point to free memory, object-start-bitmap, etc. If a valid object header is found: * If the object is not in construction, the GCInfoIndex is used the get the relevant Trace method and the object is traced. * Otherwise, the object is conservatively scanned - i.e. the payload of the object is iterated word by word and each word is treated as a possible pointer. Only addresses pointing to the payload on non-free objects are traced. BasePage::TryObjectHeaderFromInnerAddress assumes on LAB on the relevant space, thus all LABs are reset before scanning the stack.
