Log:
[29/77] Make some *_loc_descriptor helpers take scalar_int_mode

The *_loc_descriptor routines for clz, popcount, bswap and rotate
all required SCALAR_INT_MODE_P.  This patch moves the checks into
the caller (mem_loc_descriptor) so that the types of the mode
parameters can be scalar_int_mode instead of machine_mode.

The MOD handling in mem_loc_descriptor is also specific to
scalar integer modes.  Adding an explicit check allows
typed_binop to take a scalar_int_mode too.
