On x86_64 and arm64 builds Common/MsgHandler.h and Common/Logging/Log.h are
indirectly included through the corresponding VertexLoaders, Emitters
and lastly Assert.h. Because the generic build does not build a vertex
loader JIT it does not include those and fails at compile time.
Thanks to HdkR and mibofra!
Adds a cmake module to correctly discover OProfile and adjusts the
corresponding CMakeLists to make use of it. Additionally removes
linking against the bfd library when compiling with OProfile because
Dolphin does not use it.
