re PR middle-end/52940 (conversion from MODE_PARTIAL_INT uses sign extension for unsigned types)
PR middle-end/52940
* machmode.h (CLASS_HAS_WIDER_MODES_P): True for MODE_PARTIAL_INT.
* expr.c (convert_move): Honor unsignedp when extending partial int
modes.
* genmodes.c (complete_mode): Don't clear component field of partial
int modes.
(emit_mode_inner): Don't emit it however.
(calc_wider_mode): Partial int modes widen to their component.
