Inactive live ranges are ordered by their next start, so in UpdateDeferredFixedRanges, we can stop the search for conflicts as soon as the next start is after the end of the current extent of deferred code.

This CL optimizes Heap::EnsureSweepingCompleted() by only ensure that sweeping is finished for that object's page only and not for the whole heap. For this purpose the page is removed from the sweeping_list_ and processed on the main thread. In case the object is in new space, this method will just use EnsureIterabilityCompleted() since the iterability task doesn't currently have any kind of synchronization. Also the new space will generally be much smaller.

Add better support for lots of thin ticks by: * Removing stroke on ticks (so that the stroke isn't thicker than the tick itself) * Alternating colours of the ticks between light and dark (so that neighbouring ticks are still distinguishable) * Making selection drawing use isInputPending to allow faster looping over multiple ticks.

TNode has a templated constructor from TNode<U>, but this doesn't take precedence over the auto-generated copy constructor, which results in a warning being fired. Fix by adding an explicit copy constructor that does what the templated constructor does, which in turn requires fixing some missing #includes that slipped by due to the lack of LazyTemplateChecks() in the autogenerated copy constructor.

If a module is not fully (baseline) compiled yet, we cannot reliably tier it down, because we might not have the wire bytes for all functions available (in streaming compilation). After baseline compilation finished, we already check if we need to tier down, and do it then. Hence we can just skip any tier-down of unfinished modules. We cannot easily test this in V8 stand-alone, as inspector-test can only execute one command at a time, so we cannot trigger asynchronous compilation and then enable the debugger while this is running.

WireBytesStorage is the class used to access the wire bytes of a function for compilation. It is stored and passed in a shared_ptr, because it can be updated while compilation is running, and the compilation threads will keep the old reference alive until the last reference is dropped. This CL fixes a few issues where we unnecessarily passed a reference to the shared_ptr instead of just a raw pointer, and changes one copy-assign into a move-assign to avoid an unneeded reference increase and decrease.

WebAssembly functions often have subsequent memory accesses, and each of these memory accesses need the start address of the memory in a register. With this CL the register with the memory start address is cached, so only the first memory access has to load the memory start address into a register, subsequent memory accesses can just reuse the register. In first measurements with the epic benchmark this reduces the size of the generated Liftoff code by a bit more than 5%.
