Force non inline of 16 bit memory poking functions
On the Raspberry Pi 4, the compiler was inlining mempoke16 and doing
some other optimizations on it, which I presume break the memory
alignment requirements on aarch64. By adding __attribute__ ((noinline))
to the uxn functions that deal with 16 bit operations, we can turn back
-O2 compiler optimizations and the code works properly again on
hardware.
