This is a reland of e588ff10e5
The only change over the original CL is found in JSCreateLowering::AllocateFastLiteral. We now guard against boilerplate values for unboxed double fields that *look* like legitimate initial values, but should really be kHoleNanInt64 instead.
The underlying problem certainly existed before, but an invariant added to LoadElimination in this CL caused a Chromium layout test to fail. The change in this reland is therefore a workaround, the root cause remains to be fixed. Specifically, we find that a pointer to the undefined value oddball is sometimes reinterpreted as a double and assigned as a boilerplate value. @jarin suspects that this stems from in-place map updates.

This makes the WebAssembly function constructor return a proper function
object. Note that the returned object is not yet callable, only the
prototype structure is in place.

The previous logic published whenever a TurboFan function was
*finished*. Since we compile big functions first, the first TurboFan
compilation can take quite some time, and we will only publish
previously compiled Liftoff functions once that first TurboFan
compilation is done.
This CL changes that logic to publish all previous results *before*
starting a TurboFan compilation.
Drive-by: Add some trace events for interesting events.
