 SPECIALIZE strictMinimum for Int and Integer

 This fixes a regression reported in #10788, where due to less inlining
 compared to earlier versions, we’d get worse code. With the SPECIALIZE,
 we get the good code, and moreover, the good code is in List.hs and
 _not_ inlined to the use site, so smaller code size and less compilation
 time.
