[Bug ipa/128592] can_inline_edge_p checks flag_wrapv and flag_trapv but omits flag_wrapv_pointer, inlining wrapv-pointer always_inline callees into -fno-wrapv-pointer callers and folding away pointer-wrap checks

--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
Note the fix doesn't help because of

     /* Until GCC 4.9 we did not check the semantics-altering flags
        below and inlined across optimization boundaries.
        Enabling checks below breaks several packages by refusing
        to inline library always_inline functions. See PR65873.
        Disable the check for early inlining for now until better solution
        is found.  */ 
     if (always_inline && (flags & CAN_INLINE_EARLY))
        ;

so with always_inline it's a user error.  Mine.
