    [nojit] Migrate JSEntry variants to builtins · b89d4249
    Jakob Gruber authored
    This migrates the JSEntryStub to three dedicated builtins:
    
    JSEntry
    JSConstructEntry
    JSRunMicrotasksEntry
    
    Drive-by: Tweaks to make the code isolate-independent (e.g. using the
    correct macro assembler method to load and store external references
    through the kRootRegister).
    Drive-by: The context slot on x64/ia32 must be set up after
    kRootRegister is initialized, so we first reserve the slot and later
    load its value.
    Drive-by: Update all remaining comments referencing JSEntryStub.
