This is a step towards off-heap (and eventually isolate-independent) builtins. Off-heap code cannot use the standard CallStub/CallRuntime mechanisms, since they directly embed the callee code object pointer within the caller. There are two main issues with that: 1. the callee may be moved by GC, and 2. the pc-relative addressing we currently use breaks (i.e. ends up pointing to a random spot on the heap) when moving the caller off-heap. This CL addresses that by introducing a constants list stored on the roots array. Instead of embedding code targets, we now have the option of loading them from constants list. The code sequence is: REX.W movq rax,[r13+0x4a0] // Load the constants cache. REX.W movq rdx,[rax+0xf] // From there, load the code target. ... REX.W addq rdx,0x5f // Add instruction_start. call rdx There's no visible performance impact on the web tooling benchmark. This list will later be extended to also contain other constants such as Strings.

This adds a frame state for the call to the executor in inlined promise constructors. We provide a continuation function in case of deopts which just returns the created promise. This is not totally correct yet: if the executor function also throws, we need to catch it and call the reject function instead. We also still need to add a frame state for the isCallable check on the executor, so that the stack is correct for the thrown TypeError.
