V4: Collect trace information in the interpreter
Collect type information about values used in a function. These include
all parameters, and the results of many bytecode instructions. For array
loads/stores, it also tracks if the access is in-bounds of a
SimpleArrayData.
Collection is only enabled when the qml-tracing feature is turned on
while configuring.
In subsequent patches this is used to generated optimized JITted code.
