qemu/compiler: Define QEMU_ARTIFICIAL
The combination of always_inline + artificial allows tiny inline
functions to be written that do not interfere with debugging.
In particular, gdb will not step into an artificial function.
The always_inline attribute was introduced in gcc 4.2,
and the artificial attribute was introduced in gcc 4.3.
