distilled Ride.cpp testcase
In GCC 15.2 and current trunk (tested on godbolt) using `-flto=auto` prevents
`-Wnull-dereference` from reporting an error.
Originally reported as https://github.com/OpenRCT2/OpenRCT2/issues/26117
Distilled test case is provided, available online here:
https://godbolt.org/z/Gqnr5dK35.
Compile with:
`gcc -O2 -Wnull-dereference -flto-auto -c Ride.cpp` observe result differs from
when not using lto.
