Bug 1375392 - Tweak the PROFILER_LABEL* macros. r=mstange. This patch makes the following changes to the macros. - Removes PROFILER_LABEL_FUNC. It's only suitable for use in functions outside classes, due to PROFILER_FUNCTION_NAME not getting class names, and it was mostly misused. - Removes PROFILER_FUNCTION_NAME. It's no longer used, and __func__ is universally available now anyway. - Combines the first two string literal arguments of PROFILER_LABEL and PROFILER_LABEL_DYNAMIC into a single argument. There was no good reason for them to be separate, and it forced a '::' in the label, which isn't always appropriate. Also, the meaning of the "name_space" argument was interpreted in an interesting variety of ways. - Adds an "AUTO_" prefix to PROFILER_LABEL and PROFILER_LABEL_DYNAMIC, to make it clearer they construct RAII objects rather than just being function calls. (I myself have screwed up the scoping because of this in the past.) - Fills in the 'js::ProfileEntry::Category::' qualifier within the macro, so the caller doesn't need to. This makes a *lot* more of the uses fit onto a single line. The patch also makes the following changes to the macro uses (beyond those required by the changes described above). - Fixes a bunch of labels that had gotten out of sync with the name of the class and/or function that encloses them. - Removes a useless PROFILER_LABEL use within a trivial scope in EventStateManager::DispatchMouseOrPointerEvent(). It clearly wasn't serving any useful purpose. It also serves as extra evidence that the AUTO_ prefix is a good idea. - Tweaks DecodePool::SyncRunIf{Preferred,Possible} so that the labelling is done within them, instead of at their callsites, because that's a more standard way of doing things.
