* expmed.c (store_bit_field): Truncate CONST_INTs.
(expand_mult_highpart, expand_divmod): Likewise.
* expr.c (convert_modes, store_field): Likewise.
* integrate.c (expand_inline_function): Use promote_mode() to
determine whether to convert_modes() an argument as signed
or unsigned.
* optabs.c (expand_binop): Get CONST_INT operands
sign-extended for their appropriate modes.
* stmt.c (emit_case_nodes): Convert node values to the
appropriate mode.
(expand_end_case): Convert minval and range to the appropriate
mode.
* unroll.c (loop_iterations): Truncate abs_diff to the mode of
the iteration variable.
* varasm.c (immed_double_const): Don't require words to be
narrower than host wide ints to properly sign-extend
CONST_INTs.
