This implements preliminary handling of exceptions thrown by external functions that have been imported into the module.

We extracted the platform-specific API header into separate, platform- specific header files to avoid OS-specific includes in include/v8.h. As the platform-specific headers are only needed on their specific platform, we did not make them available on other platforms in BUILD.gn. Unfortunately, this is not possible, because the `include` validation in `gn gen --check` checks the availability of header files without considering `#ifdef` in the source files. Therefore the check fails on Windows when the POSIX-specific header file is not available. With this CL platform-specific headers will be generally available. This is no problem because they can only be included on their specific platform anyways.

This change lands a change to the register allocator. Other than classical linear scan, we now take control flow events into account when deciding spill descisions. The basic idea is to restore the state of a predecessor on entry of a successor. In the case of multiple predecessors, we use heuristics to compute the new state based on the predecessors. The main addition to the machinery is to support unspilling live ranges and to undo live range splitting in certain cases. Currently, disabled behind a flag.

This is a speculative fix for issue 8744. I couldn't get it to repro locally, but the stracktrace from the failing bot run points at TickSample::Init, and according to code comments in that function the value of {regs.sp} can be "arbitrary", so we must read from that address using a method that's robust towards unalignment.

TracedGlobal integrates with the use case of EmbedderHeapTracer and replaces regular weak Global or Persistent nodes for such cases. This allows to simplify the case for regular weak handles in a sense that they follow regular weak semantics (if the underlying object is otherwise unreachable the weak handle will be reset). TracedGlobal requires slightly different semantics in the sense that it can be required to keep them alive on Scavenge garbage collections because there's a transitive path that is only known when using the EmbedderHeapTracer. TracedGlobal accomodates that use case. TracedGlobal follows move semantics and can thus be used in regular std containers without wrapping data structure. The internal state uses 20% less memory and allows for only iterating those nodes when necessary. The design trades the virtual call when iterating interesting persistents in the GC prologue with calling out through the EmbedderHeapTracer for each node which is also a virtual call. There is one less iteration over the set of handles required though and the design is robust against recursive GCs that mutate the embedder state during the prologue callback.

In the trap handler we validate the list of registered code objects every time we register or de-register a new code object. The complexity of this validation is O(num-code-objects * num-instructions). For big WebAssembly modules with several hundred thousand code objects, this validation causes significant overhead (we saw up to 10x) and makes debugging very tedious. With this CL I mark the validation as slow. Thereby it is still enabled in most tests on our bots, but it is possible to disable validation when debugging large web applications. The referenced bug issue was created by developers who had problems with debugging because of this issue.

We already handle this in some locations by getting the tier before execution, so that we later know which was the requested tier for that unit. In the case of the --wasm-tier-mask-for-testing flag, this accounting was not right because the tier was already switched in the constructor.
