Subject: [Bug target/107863] [10/11/12/13 Regression] ICE with unrecognizable insn when using -funsigned-char with some SSE/AVX builtins

--- Comment #10 from Hongtao.liu <crazylht at gmail dot com> ---
I notice there's TARGET_PROMOTE_PROTOTYPES which can prevent unsigend char 255
be extended to int 255 which is a more perfect solution to this problem. But we
can only get fntype in this hook, ideally we should check fndecl to make sure
it's target specific builtins since we don't want to prevent promotion for args
in other normal functions.
