1617016 - Enhance LazyScriptCreationData to store script flags

Status: RESOLVED WORKSFORME

(Core :: JavaScript Engine, task, P2)

Description

[Matthew Gaudet (he/him) [:mgaudet]]

Today's LazyScriptCreationData::create is called before BytecodeEmission, and propagates a number of flags from the associated FunctionBox directly to the created LazyScript.

We should change this so that those flags are instead stored on the LazyScriptCreation data, so that it become independent of the FunctionBox, which will be required to support main thread stencil initialization, and the deferral of the LazyScript allocation to the end of bytecode emission.

I've marked this as dependent on Bug 1617013 to avoid having to write a whole bunch more synchronization code
