Most call signatures are small enough to keep them on the stack. This CL adds a little optimization to avoid two Zone allocations for such small signatures (and one in the general case).

At least for the initial rollout, we will gracefully handle cage reservation failures by shrinking the size of the cage until the reservation succeeds or the size drops below the mimimum cage size. This will allow collecting statistics on how often cage reservation failures occur in practice for different cage sizes, which will in turn influence the decision on how to handle them in the future.

.. for more efficient access to builtins from generated code. Root-relative accesses tend to be faster and produce more compact code when the root-relative offset is small. IsolateData contains a few large tables (roots, external references, builtins), resulting in very large offsets in general. This CL starts by splitting the builtin table into tiers: tier 0 is a minimal set of perf-critical builtins that should be cheap to access. The offset to tier 0 builtins is guaranteed to be small. The full builtin table also remains in IsolateData for occasions in which we need to lookup builtins by index. In future work, we can also split external references and roots into tiers. On x64, this reduces deopt exit sizes from 7 to 4 bytes and from 12 to 9 bytes (dynamic map checks / EagerWithResume deopts).

When dst != lhs, we moved lhs to dst, but dst can be == rhs, so we would overwrite rhs, and end up comparing lhs with itself, always returning false. We handle the different aliasing cases in the macro-assembler function I64x2GtS, to simplify the checks in Liftoff a little bit. TurboFan does not need to change as it will require dst == lhs when AVX is not supported.
