[15/77] Add scalar_int_mode
Similar to the previous scalar_float_mode patch, but for modes that
satisfy SCALAR_INT_MODE_P. There are very many uses of scalar integers,
so this patch only makes a token change to the types of byte_mode,
word_mode, ptr_mode and rs6000_pmode. The next patches in the series
gradually replace more uses.
The patch also removes and adds casts to some target-specific code
due to the new types of SImode, DImode and Pmode.
The as_a <scalar_int_mode> goes away in a later patch.
