* Remove late accesses to attribute_config

* Refactor: Extract VertexLoader from command_processor.cpp.

Preparation for a similar concept to Dolphin or PPSSPP. These can be JIT-ed and cached.

* Move "&" to their proper place, add missing includes and make some properly relative.

* Don't keep base_address in the loader, it doesn't belong there (with it, the loader can't be cached).

* Optimize the vertex loader, nearly doubling its speed.

* Debugger fix

* Move and rename the MemoryAccesses class to MemoryAccessTracker.

This has been entirely superseded by MicroProfile. The rest of the code
can go when a simpler frametime/FPS meter is added to the GUI.

* Make Citra build with MICROPROFILE_ENABLED set to 0

* Buildfix with microprofile kept on

* moc did not like a dialog to conditionally exist.

* Cleanup

* Fix end of line

Qt Frontend: Add Threads::Threads import in CMakeLists.txt

This had been forgotten in df81fa11.

Fixes #1711.

Replace std::map with std::array for graphics event breakpoints

Fixes for #1711 and other compilation errors.

This requires bumping up to a minimum of CMake 3.1. The benefit
of using the imported target is that you can switch to the -pthread
compiler flag on request, which may be necessary for some systems if
available.

Replace std::map with std::array for graphics event breakpoints, and allow the compiler to inline. Saves 1%+ in vertex heavy situations.
