Previously when we had some code like: def userCode: Unit = ... val x = myExpensiveMacro() ... The profiler reported the time spent executing the macro as `«method userCode»` which is misleading. This commit changes it to be reported as `«method myExpensiveMacro»`. This is particularly useful in bottom-up profiling to find which macros we spend the most amount of time in.
