A classic example of this would be the ARM, which has 8 bit and 32 bit
manipulation instructions but no 16 bit manipulation instructions.  A
typical C implementation for the ARM nonetheless has 16 bit shorts, so
the compiler has to do a lot of fancy footwork if you actually use
them.  In this case they are much slower than ints.
