Patch (which might depend on other patches)

I have a full fix now. The problem I mentioned is a few different issues.
First is SINGLE_BIT_MASK_OPERAND is not correct for 32bit for INT_MAX.
single_bit_mask_operand and not_single_bit_mask_operand should be using
SINGLE_BIT_MASK_OPERAND now too to correct for that also.

Next issue is riscv_build_integer_1 should not special case SImode for
!TARAGET_64BIT, it is already correct.

The next issue is riscv_build_integer_1 needs to do trunc_int_for_mode. And
then riscv_move_integer should do that also.
Last but not least riscv_emit_int_compare forgot to do trunc_int_for_mode a=
lso.=
