re PR middle-end/41268 (bootstrap is broken after r151350 (expand from tuples)) 

PR middle-end/41268
	* cfgexpand.c (expand_gimple_stmt_1): Use an int for storing
	SUBREG_PROMOTED_UNSIGNED_P, instead of a bool.
	* rtl.h (struct rtx, SUBREG_PROMOTED_UNSIGNED_P): Update comments
	to reflect reality.
