With bytecode flushing and lazy feedback allocation, we need to call
%PrepareForOptimization before we call %OptimizeFunctionOnNextCall,
ideally after declaring the function.

There were four places where we did essentially the same steps in
order to extract the initial map for inlining a JSCreate operation.
This CL creates a function on NodeProperties for this task.
As a side effect, this fixes a bug in ReduceJSCreateArray, where
has_initial_map could get called when it wasn't permissible to do so.
Notes: For simplicity, in one or two places where we used to get the
target/newtarget constants from the types we now get them from
HeapConstant nodes.
Cosmetic change: rename "receiver_map" to the more accurate
"root_map" in JSNativeContextSpecialization::ExtractReceiverMaps.
