    [builtins] Convert CEntry/GetProperty/StringAdd stubs to builtins · d8131cd6
    jgruber authored
    Stubs and builtins are very similar. The main differences are that
    stubs can be parameterized and may be generated at runtime, whereas
    builtins are generated at mksnapshot-time and shipped with the snapshot
    (or embedded into the binary).
    
    My main motivation for these conversions is that we can generate
    faster calls and jumps to (embedded) builtins callees from (embedded)
    builtin callers. Instead of going through the builtins constants table
    indirection, we can simply do a pc-relative call/jump.
    
    This also unlocks other refactorings, e.g. removal of
    CallRuntimeDelayed.
