This CL changes the poisoning in the interpreter to use the infrastructure used in the JIT. This does not change the original flag semantics: --branch-load-poisoning enables JIT mitigations as before. --untrusted-code-mitigation enables the interpreter mitigations (now realized using the compiler back-end), but does not enable the back-end based mitigations for the Javascript JIT. So in effect --untrusted-code-mitigation makes the CSA pipeline for bytecode handlers use the same mechanics (including changed register allocation) that --branch-load-poisoning enables for the JIT.
