This adds data structures to track potentially dead code in the wasm engine. The engine will then trigger an engine-wide GC once the potentially dead code reaches a certain threshold.

Since wasm optimizations are independent of JS optimizations, we can just combine the "no_liftoff" variant with the existing "stress" variant (which has the similar "--always-opt" option for JS), and add a "Liftoff only" variant as part of "nooptimization". This gives more coverage to find bugs like https://crrev.com/c/1543354 more easy.

This changes debug builds [1] to compile src/compiler sources twice: 1. with optimizations, used in mksnapshot to improve performance. 2. without optimizations, linked into d8 and v8 libraries. While this adds ~200 compilation targets, these can be built in parallel and should not add much time overall. This brings mksnapshot runtime back down to 11 seconds on my machine.

Rename the (mksnapshot-specific) --ebt-os flag to --target-os. This flag specifies the target os for mksnapshot-generated files, specifically for embedded.S. In the future we should base all of embedded-file-writer.cc on this (and an upcoming --target-arch) flag and remove other current cross-compilation workarounds (e.g.: V8_TARGET_OS_WIN, V8_TARGET_OS_FUCHSIA).

This changes the existing cctest/test-field-type-tracking tests to use actual Code objects and proper code dependencies to test that the runtime actually does the right thing (aka deoptimizes the Code objects correctly). Before it was using the CompilationDependencies, which as of now no longer check whether the runtime actually deoptimized or not. This is a prerequisite for changing the way we handle field representation changes, specifically going from Smi or HeapObject to Tagged.

This adds preliminary support for references types as argument or return values to functions that are redirected to the interpreter. The current interpreter entry stub remains unchanged, using one buffer area that is hidden from the GC. The corresponding {Runtime_WasmRunInterpreter} now correctly boxes/un-boxes reference types into handles. This switch to a handlified representation happens before any method that potentially triggers a GC is called.
