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. Change-Id: I63985c334c3fdc55fca7fb4addfe3e535989aac5 Reviewed-by: Ulf Hermann <ulf.hermann@qt.io>
