Log:
Use is_a <scalar_int_mode> for bitmask optimisations

Explicitly check for scalar_int_mode in code that checks for full-mode
bit operations.  These operations wouldn't work correctly for vector
modes, for example.  In many cases this is enforced also by checking
whether an operand is CONST_INT_P, but there were other cases where the
condition is more indirect.
