Function tcg_out_addi is obviously unused and causes a compiler

tcg/arm/tcg-target.c:1824: error: ‘tcg_out_addi’ defined but not used

Don't remove it because it might be useful in the future,
but declare it inline. This fixes the compiler error and
is similar to other tcg targets.

Ping?


I don't like that solution, it's not obvious that 'inline' should be  
reverted later.


GCC has __attribute__((unused)) for that purpose. It can be prepended  
on a line of its own so that it can be removed without touching the  
actual declaration.
