Even in streaming mode we want to generate deterministic compile
errors, in particular they should contain the function name.
This CL adds a test to check that the name is present in the error
message even if the blob containing the function names is not present
at the time the compile error is detected.

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.

The serialize set of microbenchmarks serializes Error.stack of a
prepared set of error objects. When all objects have been serialized,
the benchmark then wrapped around and only accessed the resulting
string properties. This, of course, is a lot faster and benchmark
results are heavily fluctuating when the end is reached.

This CL fixes this by introducing a payload that should be similiar
to the specific workload, which is executed after the end is reached.
