I managed to get the last obvious fix wrong: mode is M1, GET_MODE (op)
is M2.  Checking this in as obvious fix (to the obvious fix).  Let's
hope it ends here.  Tested on powerpc64-linux and powerpc64le-linux.

	* simplify-rtx.c (simplify_truncation): M2 is not mode, it is
	GET_MODE (op).  Fix this.
