Introduce compiler.h header file
This moves compiler related macros from qemu-common.h to compiler.h. The reason for this change is that there are simple header files that depend only on the compiler macros, so including qemu-common.h is overkill. Besides, qemu-common.h is bloated and will benefit from some splitting. Please, also note that the QEMU_BUILD_BUG_ON() macro is being fixed to not use double underscores as a prefix and the license text was added by Vassili Karpov (malc), who is one of the authors of the new file.
