[PUSEHED] libobjc: Add cast to void* to disable warning for casting between incompatible function types [PR89586]

[Andrew Pinski]

Even though __objc_get_forward_imp returns an IMP type, it will be casted to a 
compatable function
type before calling it. So we adding a cast to `void*` will disable warning 
about the incompatible type.

Pushed after bootstrap/test on x86_64.

libobjc/ChangeLog:

        PR libobjc/89586
        * sendmsg.c (__objc_get_forward_imp): Add cast to `void*` before 
casting to IMP.
