GHC wraps Int64 literals on 32-bit platforms when optimizing code (only happens on LLVM/C backends)
## Summary
GHC wraps Int64 literals on 32-bit platforms when enabling optimizations. This only happens on LLVM/C backends, and **not** with NCG. I have reproduced this issue in the following environments:
* GHC 9.8.2 on X86 with the LLVM backend
* Unregisterised GHC 9.8.2 on X86 (i.e., using the C backend)
* GHC 9.4.7 on armel from Debian (uses the LLVM backend)
## Steps to reproduce
```bash
$ cat Bug.hs
import Data.Int
main = do
input <- getLine
let d = (read input :: Int64)
print (d - 3000000000::Int64)
$ ghc -fllvm -o bug Bug.hs
$ echo 0 | ./bug
-3000000000
$ ghc -fllvm -o bug Bug.hs -O
$ echo 0 | ./bug
