The new API supersedes the old `RegisterDefaultSignalHandler` and flag combination. Now the embedder must explicitly call `EnableWebAssemblyTrapHandler` to activate the trap handler and optionally install the default signal handler. The old flag is now used only by D8 to decide whether to call this function.

If FLAG_enable_embedded_constant_pool is false, the field for the builtin index would alias the field for the constant pool offset in the code object. This makes constant_pool() return the builtin index, but it also makes set_constant_pool() override the builtin index (and vice versa). This CL fixes this by making all constant_pool accessors honor that flag.

Peter Marshall authored
Part of ongoing work to remove the construct_stub field of the SFI. Generate_InternalArrayConstructor was actually incorrect for packed internal arrays, where it would instead create a regular internal array because it loaded the constructor function from the context every time. Ultimately InternalArray should be removed, or the constructor ported to CSA in the meantime. But for now, it is off the critical path for the construct_stub removal. Also fix a bug: Runtime_NewArray expects a type_info parameter, which should be in rbx (on x64). Because we now go through JSBuiltinsConstructStubHelper first, rbx is loaded with a value that doesn't look like a heap object, which causes a crash in NewArray. Fix that by first loading undefined explicitly (which is what the ArrayConstructor builtin does already).

The embedders should use the EmbedderGraph API. The similar structure can be created with the following steps: 1) Create a root node for each retainer info group. 2) Iterate all handles using Isolate::VisitHandlesWithClassIds. 3) Add an edge from the retainer info node to the v8 wrapper node. 4) Add an edge from the v8 wrapper node to the retainer info node. See how HeapSnapshotRetainedObjectInfo is converted to the new API.

In general, TurboFan doesn't encounter phi nodes with only a single data input in the backend. However, CSA-based builtins (especially auto-generated ones, e.g. from Torque), may contain single-input phi nodes, although outside the auto-generated case this doesn't happen much in practice. Single input phi nodes (i.e. phis in blocks with one predecessor) don't have any side effects and are essentially useless and harmless, but to avoid problems in the backend of TurboFan (whose SSA deconstruction disallows control flow splits that continue to blocks with phis), this CL tweaks the existing CSA-only control flow and graph sanitization in the CSA path to ensure no no-op phis.
