This changes the CompileLazyDeoptimizedCode call to use the standard builtin calling sequence, which (for optimized code) creates an inlined off-heap trampoline instead of embedding a CODE_TARGET.

Recent versions of the Windows Universal CRT changed the behavior of fmod for when the first parameter is negative. In particular, a result of negative zero became positive zero. This is rarely critical but it causes test failures and may effect some JS test suites or web pages. The fix is to modify Modulo to check for a result of 0 when the first parameter is negative and change the result to -0. That fixes four of the five test failures and the fifth one is fixed by comparing the results against Modulo instead of std::fmod.

Now a descriptor array tracks the number of descriptors that were already marked. The marking visitor of a map only marks the subset of the descriptors that it needs and that are not already marked. If a descriptor array is shared between M maps and has N descriptos, then the number of marking operations is reduced from O(M*N) to O(N). This patch also adds a marking barrier for descriptors. The marked descriptor counter in a descriptor array is not cleared after mark-compact GC. Instead, it embeds two bits from the global mark-compact epoch counter and is considered 0 if the bits do not match the current value of the global epoch counter.

This CL improves load times by up to 6x. This is achieved by not setting event handlers per-line, but setting one event handler on the container.

Reachability is already being tracked in the function body decoder. This CL adds a DCHECK that the reachability tracked in the SsaEnv matches the reachability tracked in the function body decoder. Most of our methods will only be called for reachable code anyway. For exceptions, we still track reachability explicitly for now in the wasm graph builder, this can be refactored in the future by improving reachability tracking for catch blocks in the function body decoder. If this DCHECK survives fuzzing for a few days, we can remove code that handles unreachable code in graph-building-interface.cc.

We don't eagerly throw for assignments to calls; see v8:4480. They are simply turned into assignments to Property instead. We need to record a declaration error, however. Otherwise we'll end up with a Property in a declaration context. To reduce the scope of the lazy throwing, in this fix I record a pattern error instead, making calls as assignment target in a destructuring assignment context throw eagerly.
