This fixes the lowering of Reflect.getPrototypeOf and friends to not perform a [[ToObject]] coercion, but bailout instead. We ensure to exclude primitive values from the lowering.

Add support for fast - get Map.prototype.size - get Set.prototype.size by porting both the baseline implementation to the CodeStubAssembler and inlining a fast-path into TurboFan (when the compiler can infer the fact that the receiver is a proper JSCollection from the surrounding graph, i.e. from feedback gathered by a dominating LOAD_IC).

Each reducer now has a virtual reducer_name function, returning its name (the name of the class containing this reducer). This gets displayed when using the --trace_turbo_reduction flag. Also when using this flags more messages are displayed. Actually when a node is replaced in-place (which is called an update of the node), other reducers can still update it right after the in-place replacement. When a node is really replaced (not in-place), then we stop trying to apply reducers to it before we propagate the reduction through the relevant nodes. Before a message got printed only for the last reduction it went through. So in case a node was reduced in-place several times in a row, only the last update was printed, or none at all if after being reduced in-place it got reduced by being replaced by another node: only the non-in-place replacement was showed. Now each time an in-place reduction is applied to a node, a message gets printed.

This generalizes the existing support for Map and Set iteration in the CSA a bit and makes it possible to reuse the logic to implement forEach as well. It also introduces an empty_ordered_hash_table, which is used as a sentinel for exhausted iterators to avoid the need to deal with undefined there as well (not observable from JavaScript).

This Cl fixes a fundamental misunderstanding when Wasm memory histograms were added. They were added using HISTOGRAM_MEMORY_LIST(). This macro implements aggregating memory histograms that handle cases memory cases that are not module specific. The fixed memory histograms are all module specific, and are simple histograms. In addition, it removes field is_sync from ModuleCompiler and WasmCompilationUnit, since the field is no longer needed to make the fixed memory histograms synchronous.

Adds missing opcodes for exception handling for the function body decoder. Also adds error messages if the exception handling construct is not yet functional. Note that the previous prototype for catch and throw have been marked as not yet functional. This was done because it doesn't model exceptions the way the proposal suggests. Rather, they implement a hard-coded (c++ model) of exceptions.

This improves the general Array constructor call performance (w/o usable AllocationSite feedback) in TurboFan by ~2x, i.e. for example invoking the Array constructor like this var a = Array.call(undefined, n); instead of var a = Array(n); such that the CallIC doesn't know that it's eventually calling the Array constructor. It also thus changes the single argument Array constructor to always return holey arrays. Previously the single argument case for the Array constructor was somehow trying to dynamically detect 0 and in that case returned a packed array instead of a holey one. That adds quite a lot of churn, and doesn't seem to be very useful, especially since this might lead to unnecessary feedback pollution later.

In https://chromium-review.googlesource.com/c/472247/, I avoided running DesugarLexicalBindingsInForStatement() if there were no lexical loop variables, the function was not resumable, and the variables are not captured by eval or a function declaration. I think it's now possible to limit this further, and only do the more extensive desugaring if there's a function declaration / eval() call in the loop body. `yield` and `await` are not an issue as those loop variables are written to the register file and not lost. This change just removes the `is_resumable()` condition. If it passes tests, I think it's safe.

The use of double variables to store bit patterns may lead to bit flips when the stored bit pattern is a signaling NaN (sNaN). Operations on a sNaN variable (even just returning the variable from a function) may turn it into a quiet NaN (qNaN), flipping the signaling bit and affecting the information stored in the variable. We observed this behaviour on ia32 architectures and therefore in the simulator builds for other platforms. The use of the wrapper class Double should prevent this behaviour.
